The control of invertebrate pests is extremely important in achieving high crop efficiency. Damage by invertebrate pests to growing and stored agronomic crops can cause significant reduction in productivity and thereby result in increased costs to the consumer.

The control of invertebrate pests in forestry, greenhouse crops, ornamentals, nursery crops, stored food and fiber products, livestock, household, and public and animal health is also important. Many products are commercially available for these purposes, but the need continues for new compounds that are more effective, less costly, less toxic, environmentally safer or have different modes of action.

As indicated in the Summary of the Invention, the cycloalkyl in cycloalkylamino and (alkyl) cycloalkylamino is C3-C6 cycloalkyl, while the alkyl in (alkyl) cycloalkylamino is C1-C4 alkyl.

The term"aromatic"indicates that each of the ring atoms is essentially in the same plane and has ap-orbital perpendicular to the ring plane, and in which (4n + 2) S electrons, when n is 0 or a positive integer, are associated with the ring to comply with Huckel's rule.

The term"aromatic ring system"denotes fully unsaturated carbocycles and heterocycles in which at least one ring of a polycyclic ring system is aromatic. Aromatic carbocyclic ring or fused carbobicyclic ring systems includes fully aromatic carbocycles and carbocycles in which at least one ring of a polycyclic ring system is aromatic (e. g. phenyl and naphthyl).

The term"nonaromatic carbocyclic ring"denotes fully saturated carbocycles as well as partially or fully unsaturated carbocycles where the Huckel rule is not satisfied by the ring.

The term"hetero"in connection with rings or ring systems refers to a ring or ring system in which at least one ring atom is not carbon and which can contain 1 to 4 heteroatoms independently selected from the group consisting of nitrogen, oxygen and sulfur, provided that each ring contains no more than 4 nitrogens, no more than 2 oxygens and no more than 2 sulfurs. The terms"heteroaromatic ring or ring system"and"aromatic fused heterobicyclic ring system"includes fully aromatic heterocycles and heterocycles in which at least one ring of a polycyclic ring system is aromatic (where aromatic indicates that the Huckel rule is satisfied). The term"nonaromatic heterocyclic ring or ring system"denotes fully saturated heterocycles as well as partially or fully unsaturated heterocycles where the Huckel rule is not satisfied by any of the rings in the ring system. The heterocyclic ring or ring system can be attached through any available carbon or nitrogen by replacement of a hydrogen on said carbon or nitrogen.

The term"halogen", either alone or in compound words such as"haloalkyl", includes fluorine, chlorine, bromine or iodine. Further, when used in compound words such as "haloalkyl", said alkyl may be partially or fully substituted with halogen atoms which may be the same or different. Examples of "haloalkyl" include F3C, ClCH2, CF3CH2 and CF3CC12. The terms"haloalkenyl","haloalkynyl","haloalkoxy", and the like, are defined analogously to the term"haloalkyl". Examples of"haloalkenyl"include (C1) 2C=CHCH2 and CF3CH2CH=CHCH2. Examples of"haloalkynyl"include HC-CCHCl, CF3C=C, CCl3C-C and FCH2C-CCH2.

Examples of"dialkylaminocarbonyl"include (CH3) 2NC (=O), (CH3CH2) 2NC (=O), CH3CH2 (CH3) NC (=O), CH3CH2CH2 (CH3) NC (=O) and (CH3) 2CHN (CH3) C (=O).

The total number of carbon atoms in a substituent group is indicated by the"Ci-Cj" prefix where i and j are numbers from 1 to 8. For example, C 1-C4. alkylsulfonyl designates methylsulfonyl through butylsulfonyl ; C2 alkoxyalkyl designates CH30CH2 ; C3 alkoxyalkyl designates, for example, CH3CH(OCH3), CH3OCH2CH2 or CHgCH20CH2 ; and C4 alkoxyalkyl designates the various isomers of an alkyl group substituted with an alkoxy group containing a total of four carbon atoms, examples including CH3CH2CH20CH2 and CH3CH20CH2CH2. In the above recitations, when a compound of Formula I comprises a heterocyclic ring, all substituents are attached to this ring through any available carbon or nitrogen by replacement of a hydrogen on said carbon or nitrogen.

When a compound is substituted with a substituent bearing a subscript that indicates the number of said substituents can exceed 1, said substituents (when they exceed 1) are independently selected from the group of defined substituents. Further, when the subscript indicates a range, e. g. (R) i-j, then the number of substituents may be selected from the integers between i and j inclusive.

The term"optionally substituted"indicates that a moiety may be substituted or unsubstituted. The term"optionally substituted with from one to three substituents"and the like indicates that the moiety may be unsubstituted or from one to three of the available positions on the moiety may be substituted. When a moiety contains a substituent which can

be hydrogen, for example R4, then, when this substituent is taken as hydrogen, it is recognized that this is equivalent to said moiety being unsubstituted.

Compounds of Formula I can exist as one or more stereoisomers. The various stereoisomers include enantiomers, diastereomers, atropisomers and geometric isomers. Of note are geometric isomers in which R2 of the imino moiety may be s) ; n or anti relative to B, or a mixture of syn and ant geometric isomers. One skilled in the art will appreciate that one stereoisomer may be more active and/or may exhibit beneficial effects when enriched relative to the other stereoisomer (s) or when separated from the other stereoisomer (s).

Additionally, the skilled artisan knows how to separate, enrich, and/or to selectively prepare said stereoisomers. Accordingly, the compounds of Formula I may be present as a mixture of stereoisomers, individual stereoisomers, or as an optically active form. Some compounds of Formula I can exist as one or more tautomers, and all tautomeric forms of such compounds are part of the present invention. Accordingly, the compounds of the invention may be present as a mixture of tautomers or the individual tautomers.

The present invention comprises compounds selected from Formula I, N-oxides and salts thereof. One skilled in the art will appreciate that not all nitrogen containing heterocycles can form N-oxides since the nitrogen requires an available lone pair of electrons for oxidation to the oxide; one skilled in the art will recognize those nitrogen containing heterocycles which can form N-oxides. One skilled in the art will also recognize that tertiary amines can form N-oxides. Synthetic methods for the preparation of N-oxides of heterocycles and tertiary amines are very well known by one skilled in the art including the oxidation of heterocycles and tertiary amines with peroxy acids such as peracetic and m-chloroperbenzoic acid (MCPBA), hydrogen peroxide, alkyl hydroperoxides such as t-butyl hydroperoxide, sodium perborate, and dioxiranes such as dimethydioxirane. These methods for the preparation of N-oxides have been extensively described and reviewed in the literature, see for example: T. L. Gilchrist in Comprehensive Organic Synthesis, vol. 7, pp 748-750, S. V. Ley, Ed. , Pergamon Press; M. Tisler and B. Stanovnik in Comprehensive Heterocyclic Chemisty, Vol. 3, pp 18-19, A. J. Boulton and A. McKillop, Eds. , Pergamon Press ; M. R. Grimmett and B. R. T. Keene in Advances n Heterocyclic Chemistey, Vol. 43, pp 139-151, A. R. Katritzky, Ed. , Academic Press; M. Tisler and B. Stanovnik in Advances in Heterocyclic Chemist7y, Vol. 9, pp 285-291, A. R. Katritzky and A. J. Boulton, Eds., Academic Press; and G. W. H. Cheeseman and E. S. G. Werstiuk inAdvances in Heterocyclic Chemistry, Vol. 22, pp 390-392, A. R. Katlitzky and A. J. Boulton, Eds. , Academic Press.

The salts of the compounds of the invention include acid-addition salts with inorganic or organic acids such as hydrobromic, hydrochloric, nitric, phosphoric, sulfuric, acetic, butyric, fumaric, lactic, maleic, malonic, oxalic, propionic, salicylic, tartaric, 4-toluenesulfonic or valeric acids. The salts of the compounds of the invention also include

those formed with organic bases (e. g. , pyridine, ammonia, or triethylamine) or inorganic bases (e. g. , hydrides, hydroxides, or carbonates of sodium, potassium, lithium, calcium, magnesium or barium) when the compound contains an acidic moiety such as a carboxylic acid or phenol.

As noted above, J is a phenyl ring, a naphthyl ring system, a 5-or 6-membered heteroaromatic ring or an aromatic 8-, 9-or 10-membered fused heterobicyclic ring system wherein each ring or ring system is optionally substituted with 1 to 4 R5. The term "optionally substituted"in connection with these J groups refers to groups which are unsubstituted or have at least one non-hydrogen substituent that does not extinguish the biological activity possessed by the unsubstituted analog. An example of phenyl optionally substituted with 1 to 4 R5 is the ring illustrated as U-1 in Exhibit 1, wherein Rv is R5 and r is an integer from 0 to 4. An example of a naphthyl group optionally substituted with 1 to 4 R5 is illustrated as U-85 in Exhibit 1, wherein Rv is R5 and r is an integer from 0 to 4.

Examples of 5-or 6-membered heteroaromatic rings optionally substituted with 1 to 4 R5 include the rings U-2 through U-53 illustrated in Exhibit 1 wherein Rv is R5 and r is an integer from 0 to 4. Note that J-1 through J-5 below also denote 5-or 6-membered heteroaromatic rings.

Examples of aromatic 8-, 9-or 10-membered fused heterobicyclic ring systems optionally substituted with 1 to 4 R5 include U-54 through U-84 illustrated in Exhibit 1 wherein Rv is R5 and r is an integer from 0 to 4.

The nitrogen atoms that require substitution to fill their valence are substituted with H or Rv. Note that some U groups can only be substituted with less than 4 Rv groups (e. g. U- 14, U-15, U-18 through U-21 and U-32 through U-34 can only be substituted with one Rv).

Note that when the attachment point between (RV) r and the U group is illustrated as floating, (RV) r can be attached to any available carbon atom of the U group. Note that when the attachment point on the U group is illustrated as floating, the U group can be attached to the remainder of Formula I through any available carbon of the U group by replacement of a hydrogen atom.

Examples of such G groups include those illustrated as G-1 through G-41 in Exhibit 2 wherein m is an integer from 0 to 4. The term"optionally substituted"in connection with these C groups refers to groups which are unsubstituted or have at least one non-hydrogen substituent that does not extinguish the biological activity possessed by the unsubstituted analog. Note that when the attachment point on these G groups is illustrated as floating, the G group can be attached to the remainder of Formula I through any available carbon or nitrogen of the G group by replacement of a hydrogen atom. The optional substituents can be attached to any available carbon or nitrogen by replacing a hydrogen atom. Note that when G comprises a ring selected from G-24 through G-29 and G-32 through G-35, A is selected from 0, S or NR3. Note that when G is G-3, G-5, G-7, G-9, G-16 through G-18, G- 23, and G-24 through G-29, and G-32 through G-35 (when A is NR3), the nitrogen atoms that require substitution to fill their valence are substituted with H or R3.

Examples of optionally substituted RI and/or R2 groups are those that are optionally substituted by replacement of a hydrogen on a carbon atom of the Rl and/or R2 group with one or more (up to the total number of hydrogens available for replacement in any specific Rl and/or R2 group) substituents independently selected from the substituents listed in the Summary of the Invention above. Although these substituents are listed, it is noted that they do not need to be present since they are optional substituents. Of note are Rl and/or R2 groups that are unsubstituted.

Examples of such substituents include the rings illustrated as U-1 through U-53 and U-88 illustrated in Exhibit 1, except that such rings are optionally substituted with 1 to 3 substituents independently selected from R6 rather than (RV) r. Note that R6 substituents do not need to be present since they are optional substituents.

As noted above, each R4 is independently (among others) a phenyl, benzyl, phenoxy or a 5-or 6-membered heteroaromatic ring, each ring optionally substituted with one to three substituents independently selected from R6. The term"optionally substituted"in connection with these R4 groups refers to groups which are unsubstituted or have at least one non-hydrogen substituent that does not extinguish the biological activity possessed by the unsubstituted analog. Examples of such R4 groups include the rings illustrated as U-1 through U-53, U-86 and U-88 illustrated in Exhibit 1, except that such rings are optionally substituted with 1 to 3 substituents independently selected from R6 rather than (Rr.

The definitions of B, J, V, RI through R6 and n in the compounds of Formulae I, II and 2-96 below are as defined above in the Summary of the Invention. Compounds of FormulaeIa-f, IIa-c, 3a, 4a-t, 10a, 18a, 19a-c and 20a are various subsets of the compounds of Formula I, II, 3,4, 10, 18,19 and 20, respectively.

This cyclization is typically conducted in solvents such as dichloroethane, dichloromethane, chloroform, benzene, toluene, xylenes, hexanes, cyclohexane, 1,4-dioxane, tetrahydrofuran and chlorobenzene in the temperature range from 0 °C to the reflux temperature of the mixture. Alternatively, the dehydrative cyclization can be effected by treatment of Formula IIa or Formula lIb with triphenyl phosphine and either bromine or iodine, optionally in the presence of tertiary amine bases such as triethylamine or diisopropylethylamine. SeeMonatsh. Chem. 1989,120, 973-980 andJ. Org Chem. 2000, 65,1022-1030 for representative procedures.

Typical acid scavengers include amine bases such as triethylamine, diisopropylethylamine and pyridine ; other scavengers include hydroxides such as sodium and potassium hydroxide and carbonates such as sodium carbonate and potassium carbonate. In certain instances it is useful to use polymer-supported acid scavengers such as polymer-bound diisopropylethyl- amine and polymer-bound dimethylaminopyridine. The coupling can be run in a suitable inert solvent such as tetrahydrofuran, dioxane, diethylether or dichloromethane to afford the anilide of Formula IIa.

In a subsequent step, amides of Formula IIa can be converted to thioamides of Formula IIb using a variety of standard thio transfer reagents including phosphorus pentasulfide and Lawesson's reagent.

Polymer supported reagents are again useful here, such as polymer-bound cyclohexylcarbodiimide. The coupling can be run in a suitable inert solvent such as dichloromethane or N, N-dimethylformamide. Synthetic procedures of Schemes 2 and 3 are only representative examples of useful methods for the preparation of Formula II compounds as the synthetic literature is extensive for this type of reaction.

For example, acid chlorides of Formula 3 are readily made from carboxylic acids of Formula 4 by reacting the carboxylic acid 4 with thionyl chloride or oxalyl chloride in an inert solvent such as toluene or dichloromethane in the presence of a catalytic amount of NN-dimethylformamide.

Amines of Formula 2 are typically available from the corresponding 2-nitrobenzamides of Formula 5 via catalytic hydrogenation of the nitro group (Scheme 4).

Typical procedures involve reduction with hydrogen in the presence of a metal catalyst such as palladium on carbon or platinum oxide and in hydroxylic solvents such as ethanol and

isopropanol. They can also be prepared by reduction with zinc in acetic acid. These procedures are well documented in the chemical literature.

Typical methods for amide formation can be applied here. These include direct dehydrative coupling of acids of Formula 6 with amines of Formula 7 using for example DCC, and conversion of the acids to activated forms such as the acid chlorides or anhydrides and subsequent coupling with amines to form amides of Formula 5. Alkyl chloroformates, such as ethyl chloroformate or isopropyl chloroformate, are especially useful reagents for this type of reaction involving activation of the acid. The chemical literature is extensive on methods for amide formation.

Typical procedures involve combination of equimolar amounts of the amine 7 with the isatoic anhydride in polar aprotic solvents such as pyridine and N, N-dimethylformamide at temperatures ranging from room temperature to 100 °C. Isatoic anhydrides of Formula 8 may be made by methods described in Coppola, Synthesis 1980,505-36.

Scheme 6 As shown in Scheme 7, an alternate procedure for the preparation of compounds of Formula IIa involves reaction of an amine of Formula 7 with a benzoxazinone of Formula 10. The reaction of Scheme 7 can be run neat or in a variety of suitable solvents including tetrahydrofuran, diethyl ether, pyridine, dichloromethane or chloroform with optimum temperatures ranging from room temperature to the reflux temperature of the solvent. The general reaction of benzoxazinones with amines to produce anthranilamides is well documented in the chemical literature. For a review of benzoxazinone chemistry see Jakobsen et al., Biorganic and Medicinal Chenaistfy 2000, 8, 2095-2103 and references cited therein. See also Coppola, J. Heterocyclic Chemistry 1999, 36, 563-588.

Scheme 7 Benzoxazinones of Formula 10 can be prepared by a variety of procedures. Two procedures that are especially useful are detailed in Schemes 8 and 9. In Scheme 8, a benzoxazinone of Formula 10 is prepared directly via coupling of a carboxylic acid of Formula 4 with an anthranilic acid of Formula 11. This involves sequential addition of methanesulfonyl chloride to a carboxylic acid of Formula 4 in the presence of an amine base such as triethylamine or pyridine, followed by the addition of an anthranilic acid of Formula 1 l, followed by a second addition of triethylamine and methanesulfonyl chloride.

This procedure generally affords good yields of the benzoxazinone and is especially useful for preparing compounds of Formula lOa from pyrazolecarboxylic acids of Formula 4a.

Scheme 9 depicts an alternate preparation for benzoxazinones of Formulae 10 and lOa involving coupling of an acid chloride of Formula 3 with an isatoic anhydride of Formula 8 to provide the Formula 10 benzoxazinone directly. Compounds of Formula lOa can be prepared from the pyrazole acid chloride of Formula 3a by a similar procedure. Solvents such as pyridine or pyridine/acetonitrile are suitable for this reaction. The acid chlorides of Formula 3 a are available from the corresponding acids of Formula 4a by known procedures such as chlorination with thionyl chloride or oxalyl chloride.

Isatins of Formula 13 are available from aniline derivatives of Formula 12 following literature procedures. Oxidation of isatin 13 with hydrogen peroxide generally affords good yields of the corresponding isatoic anhydride 8 (ange. Chent. Int. Ed. Eiigl. 1980, 19, 222-223). Isatoic anhydrides are also available from

the anthranilic acids 11 via many known procedures involving reaction of 11 with phosgene or a phosgene equivalent.

Scheme 10 Compounds of Formula Ic or Id (compounds of Formula I wherein B is NR1) can be prepared from anthranilonitriles of Formula 14 by cyclization with an amide of Formula 15 in the presence of dehydration agents such as POC13, POClg/PCl5 or SOC12 (Scheme 11).

This cyclization is typically conducted in solvents such as dichloroethane, dichloromethane, chloroform, benzene, toluene, xylenes, hexanes, cyclohexane, 1, 4-dioxane, tetrahydrofuran and chlorobenzene in the temperature range from 0 °C to the reflux temperature of the mixture. The resultant compounds of Formula Ic (wherein R2 is H) can be treated with electrophiles of Formula 16 (wherein Lg is a leaving group such as halogen and alkyl or aryl suphonates), optionally in the presence of an acid scavenger, to provide compounds of Formula Id (wherein R2 is other than H). Typical acid scavengers include amine bases such as triethylamine, diisopropylethylamine and pyridine; other scavengers include hydroxides such as sodium and potassium hydroxide and carbonates such as sodium carbonate and potassium carbonate. In certain instances it is useful to use polymer-supported acid scavengers such as polymer-bound diisopropylethylamine and polymer-bound dimethylaminopyridine. These reactions are typically conducted in solvents such as dichloroethane, dichloromethane, chloroform, benzene, toluene, xylenes, hexanes, cyclohexane, 1, 4-dioxaneatetrahydrofurandimethylsufoxideN, N-dimethylformamide, N, N-dimethylacetamide and chlorobenzene in the temperature range from 0 °C to the reflux temperature of the mixture. Compounds of Formula Id may be prepared from compounds of Formulae 14 and 15 (wherein Rl is H) by similar procedures. Alkylation of Formula Id with an alkylating agent with two leaving groups (e. g. ethylene dibromide or propylene bromide) provides compounds of Formula Ie wherein, for example, the moiety Rl-R2 is CH2CH2 or CH2CH2CH2

They can be prepared via 3+2 cycloaddition of an appropriately substituted nitrilimine of Formula 24 with either substituted propiolates of Formula 25 or acrylates of Formula 27.

Cycloaddition with an acrylate requires additional oxidation of the intermediate pyrazoline to the pyrazole. Hydrolysis of the esters of Formula 28 affords the pyrazole acids of Formula 4c. Preferred iminohalides for this reaction include the trifluoromethyl iminochloride of Formula 29 and the iminodibromide of Formula 30. Compounds such as 29 are known (I. Heterocycl. Chena. 1985,22 (2), 565-8). Compounds such as 30 are available by known methods (Tetrahedro7 Letters 1999, 40, 2605). These procedures are particularly useful for the preparation of compounds where R5a is optionally substituted phenyl and R5b is haloalkyl or bromo.

The starting pyrazoles of Formula 19 are known compounds or can be prepared according to known methods. The pyrazole of Formula 19a (the compound of Formula 19 wherein R5b is CF3 and R5c is H) is commercially available. The pyrazoles of Formula 19c (compounds of Formula 19 wherein R5b is Cl or Br and R5c is H) can be prepared by literature procedures (Chem. Ber. 1966, 99 (10), 3350-7).

Reaction of a compound of Formula 81 wherein R12 is C1-C4 alkyl with a suitable base in a suitable organic solvent affords the cyclized product of Formula 82 after neutralization with an acid such as acetic acid. The suitable base can be, for example but not limitation, sodium hydride, potassium t-butoxide, dimsyl sodium (CH3S (O) CH2-Na », alkali metal (such as lithium, sodium or potassium) carbonates or hydroxides, tetraalkyl (such as methyl, ethyl or butyl) ammonium fluorides or hydroxides, or 2-tert-butylimino-2-diethylamino-1, 3-dimethyl- perhydro-1, 3,2-diazaphosphonine. The suitable organic solvent can be, for example but not

limitation, acetone, acetonitrile, tetrahydrofuran, dichloromethane, dimethylsulfoxide, or N, N-dimethylformamide. The cyclization reaction is usually conducted in a temperature range from about 0 to 120 °C.

A preferred base is tetrabutylammonium fluoride.

Dehydration of the compound of Formula 82 to give the compound of Formula 83, followed by converting the carboxylic ester function to carboxylic acid, affords the compound of Formula 4q.

As one skilled in the art will realize, dehydration reactions may be conducted in a wide variety of solvents in a temperature range generally between about 0 and 200 °C, more preferably between about 0 and 100 °C). For the dehydration in the method of Scheme 30, a solvent comprising acetic acid and temperatures of about 65 °C are preferred. Carboxylic ester compounds can be converted to carboxylic acid compounds by numerous methods including nucleophilic cleavage under anhydrous conditions or hydrolytic methods involving the use of either acids or bases (see T.

Oxidization of the compound of Formula 88 optionally in the presence of acid to give the compound of Formula 89 followed by conversion of the carboxylic ester function to the carboxylic acid provides the compound of Formula 4r. The oxidizing agent can be hydrogen peroxide, organic peroxides, potassium persulfate, sodium persulfate, ammonium persulfate, potassium monopersulfate (e. g., Oxone@) or potassium permanganate. To obtain complete conversion, at least one equivalent of oxidizing agent versus the compound of Formula 88 should be used, preferably between about one to two equivalents. This oxidation is typically carried out in the presence of a solvent. The solvent can be an ether, such as tetrahydrofuran, p-dioxane and the like, an organic ester, such as ethyl acetate, dimethyl carbonate and the like, or a polar aprotic organic such as N, N-dimethylformamide, acetonitrile and the like.

Acids suitable for use in the oxidation step include inorganic acids, such as sulfuric acid, phosphoric acid and the like, and organic acids, such as acetic acid, benzoic acid and the like. The acid, when used, should be used in greater than 0.1 equivalents versus the compound of Formula 88. To obtain complete conversion, one to five equivalents of acid

can be used. The preferred oxidant is potassium persulfate and the oxidation is preferably carried out in the presence of sulfuric acid. The reaction can be carried out by mixing the compound of Formula 88 in the desired solvent and, if used, the acid. The oxidant can then be added at a convenient rate.

Preferred are phosphorus oxyhalides and phosphorus pentahalides. To obtain complete conversion, at least 0.33 equivalents of phosphorus oxyhalide versus the compound of Formula 90 should be used, preferably between about 0. 33 and 1.2 equivalents. To obtain complete conversion, at least 0.20 equivalents of phosphorus pentahalide versus the compound of Formula 90 should be used, preferably between about 0.20 and 1.0 equivalents. Compounds of Formula 90 wherein R12 is Cl-C4 alkyl are preferred for this reaction. Typical solvents for this halogenation include halogenated alkanes, such as dichloromethane, chloroform, chlorobutane and the like, aromatic solvents, such as benzene, xylene, chlorobenzene and the like, ethers, such as tetrahydrofuran, p-dioxane, diethyl ether, and the like, and polar aprotic solvents such as acetonitrile, N, N-dimethylformamide, and the like. Optionally, an organic base, such as triethylamine, pyridine, N, N-dimethylaniline or the like, can be added. Addition of a

catalyst, such as N, N-dimethylformamide, is also an option. Preferred is the process in which the solvent is acetonitrile and a base is absent. Typically, neither a base nor a catalyst is required when acetonitrile solvent is used. The preferred process is conducted by mixing the compound of Formula 90 in acetonitrile. The halogenating reagent is then added over a convenient time, and the mixture is then held at the desired temperature until the reaction is complete. The reaction temperature is typically between 20 °C and the boiling point of acetonitrile, and the reaction time is typically less than two hours. The reaction mass is then neutralized with an inorganic base, such as sodium bicarbonate, sodium hydroxide and the like, or an organic base, such as sodium acetate. The desired product, a compound of Formula 88, can be isolated by methods known to those skilled in the art, including crystallization, extraction and distillation.

Alternatively, compounds of Formula 88 wherein R7 is Br or Cl can be prepared by treating the corresponding compounds of Formula 88 wherein R7 is a different halogen (e. g., Cl for making Formula 88 wherein R7 is Br) or a sulfonate group such as p-toluenesulfonate with hydrogen bromide or hydrogen chloride, respectively. By this method the R7 halogen or sulfonate substituent on the Formula 88 starting compound is replaced with Br or Cl from hydrogen bromide or hydrogen chloride, respectively. The reaction is conducted in a suitable solvent such as dibromomethane, dichloromethane or acetonitrile. The reaction can be conducted at or near atmospheric pressure or above atmospheric pressure in a pressure vessel. When R7 in the starting compound of Formula 88 is a halogen such as Cl, the reaction is preferably conducted in such a way that the hydrogen halide generated from the reaction is removed by sparging or other suitable means. The reaction can be conducted between about 0 and 100 °C, most conveniently near ambient temperature (e. g. , about 10 to 40 °C), and more preferably between about 20 and 30 °C. Addition of a Lewis acid catalyst (such as aluminum tribromide for preparing Formula 88 wherein R7 is Br) can facilitate the reaction. The product of Formula 88 is isolated by the usual methods known to those skilled in the art, including extraction, distillation and crystallization.

Starting compounds of Formula 88 wherein R7 is Cl or Br can be prepared from corresponding compounds of Formula 90 as already described. Starting compounds of Formula 88 wherein R7 is a sulfonate group can likewise be prepared from corresponding compounds of Formula 90 by standard methods such as treatment with a sulfonyl chloride (e. g., p-toluenesulfonyl chloride) and base such as a tertiary amine (e. g. , triethylamine) in a suitable solvent such as dichloromethane.

Pyrazolecarboxylic acids of Formula 4s wherein R7 is OCH2CF3 or Formula 4t wherein R7 is OCHF2 can be prepared by the method outlined in Scheme 34. In this method, instead of being halogenated as shown in Scheme 33, the compound of Formula 90 is oxidized to the compound of Formula 91. The reaction conditions for this oxidation are as

already described for the conversion of the compound of Formula 88 to the compound of Formula 89 in Scheme 32.

The compound of Formula 91 is then alleviated to form the compound of Formula 93 (R7 is OCH2CF3) by contact with an alkylating agent CF3CH2Lg (92) in the presence of a base. In the alkylating agent 92, Lg is a nucleophilic reaction leaving group such as halogen (e. g. , Br, I), OS (O) 2CH3 (methanesulfonate), OS (O) 2CF3, OS (O) 2Ph-p-CH3 (p-toluenesulfonate), and the like; methanesulfonate works well. The reaction is conducted in the presence of at least one equivalent of a base. Suitable bases include inorganic bases, such as alkali metal (such as lithium, sodium or potassium) carbonates and hydroxides, and organic bases, such as triethylamine, diisopropylethylamine and 1, 8-diazabicyclo [5.4. 0] - undec-7-ene. The reaction is generally conducted in a solvent, which can comprise alcohols, such as methanol and ethanol, halogenated alkanes, such as dichloromethane, aromatic solvents, such as benzene, toluene and chlorobenzene, ethers, such as tetrahydrofuran, and polar aprotic solvents, such as acetonitrile, N, N-dimethylformamide, and the like. Alcohols and polar aprotic solvents are preferred for use with inorganic bases. Potassium carbonate as base and acetonitrile as solvent are preferred. The reaction is generally conducted between about 0 and 150 °C, with most typically between ambient temperature and 100 °C.

The compound of Formula 91 can also be alkylated to form the compound of Formula 95 (R7 is OCHF2) by contact with difluorocarbene, prepared from CHC1F2 in the presence of a base. The reaction is generally conducted in a solvent, which can comprise ethers, such as tetrahydrofuran or dioxane, and polar aprotic solvents, such as acetonitrile, N, N-dimethylformamide, and the like. The base can be selected from inorganic bases such as potassium carbonate, sodium hydroxide or sodium hydride. Preferably the reaction is conducted using potassium carbonate with N, N-dimethylformamide as the solvent. The esters of Formula 93 or 95 can be isolated by conventional techniques such as extraction.

The esters can then be converted to the carboxylic acids of Formula 4 or 4t by the methods already described for the conversion of Formula 83 to Formula 4q in Scheme 30.

As outlined in Scheme 35, compounds of Formula 90 can be prepared from compounds of Formula 84 (see Scheme 31).

Scheme 35 H R6 f R12o--CHCo2Rl2 > 90 -11 96 84 wherein R12 is C. 1-C4 alkyl.

In this method, a hydrazine compound of Formula 84 is contacted with a compound of Formula 96 (a fumarate ester or maleate ester or a mixture thereof may be used) in the presence of a base and a solvent. The base is typically a metal alkoxide salt, such as sodium methoxide, potassium methoxide, sodium ethoxide, potassium ethoxide, potassium tert-butoxide, lithium tert-butoxide, and the like. Greater than 0. 5 equivalents of base versus the compound of Formula 84 should be used, preferably between 0.9 and 1.3 equivalents.

Greater than 1.0 equivalents of the compound of Formula 96 should be used, preferably between 1.0 to 1.3 equivalents. Polar protic and polar aprotic organic solvents can be used, such as alcohols, acetonitrile, tetrahydrofuran, N, N-dimethylformamide, dimethyl sulfoxide and the like. Preferred solvents are alcohols such as methanol and ethanol. It is especially preferred that the alcohol be the same as that making up the fumarate or maleate ester and the alkoxide base. The reaction is typically conducted by mixing the compound of Formula 84 and the base in the solvent. The mixture can be heated or cooled to a desired temperature and the compound of Formula 96 added over a period of time. Typically reaction temperatures are between 0 °C and the boiling point of the solvent used. The

reaction may be conducted under greater than atmospheric pressure in order to increase the boiling point of the solvent. Temperatures between about 30 and 90 °C are generally preferred. The addition time can be as quick as heat transfer allows. Typical addition times are between 1 minute and 2 hours. Optimum reaction temperature and addition time vary depending upon the identities of the compounds of Formula 84 and Formula 96. After addition, the reaction mixture can be held for a time at the reaction temperature. Depending upon the reaction temperature, the required hold time may be from 0 to 2 hours. Typical hold times are 10 to 60 minutes. The reaction mass then can be acidified by adding an organic acid, such as acetic acid and the like, or an inorganic acid, such as hydrochloric acid, sulfuric acid and the like. Depending on the reaction conditions and the means of isolation, the-C02R12 function on the compound of Formula 90 may be hydrolyzed to-C02H ; for example, the presence of water in the reaction mixture can promote such hydrolysis. If the carboxylic acid (-C02H) is formed, it can be converted back to-C02R12 wherein R12 is Cl-C4 alkyl using esterification methods well known in the art. The desired product, a compound of Formula 90, can be isolated by methods known to those skilled in the art, such as crystallization, extraction or distillation.

It is recognized that some reagents and reaction conditions described above for preparing compounds of Formula I may not be compatible with certain functionalities present in the intermediates. In these instances, the incorporation of protection/deprotection sequences or functional group interconversions into the synthesis will aid in obtaining the desired products. The use and choice of the protecting groups will be apparent to one skilled in chemical synthesis (see, for example, Greene, T. W.; Wuts, P. G. M. Protective Groups in Organic Synthesis, 2nd ed.; Wiley: New York, 1991). One skilled in the art will recognize that, in some cases, after the introduction of a given reagent as it is depicted in any individual scheme, it may be necessary to perform additional routine synthetic steps not described in detail to complete the synthesis of compounds of Formula I. One skilled in the art will also recognize that it may be necessary to perform a combination of the steps illustrated in the above schemes in an order other than that implied by the particular sequence presented to prepare the compounds of Formula I.

It is believed that one skilled in the art using the preceding description can prepare compounds of Formula I of the present invention to its fullest extent.

The reaction was cooled to 100 °C and filtered through Celiez diatomaceous filter aid to remove solids. NN-Dimethylformamide and excess dichloropyridine were removed by distillation at atmospheric pressure. Distillation of the product at reduced pressure (b. p. 139-141 °C, 7 mm) afforded the desired intermediate as a clear yellow oil (113.4 g).

The deep red solution was stirred for 15 minutes, after which time carbon dioxide was bubbled through at 63 °C until the solution became pale yellow and the exothermicity ceased. The reaction was stirred for an additional 20 minutes and then quenched with water (20 mL). The solvent was removed under reduced pressure, and the reaction mixture partitioned between ether and 0.5 N aqueous sodium hydroxide solution. The aqueous extracts were washed with ether (3x), filtered through Celiez diatomaceous filter aid to remove residual solids, and then acidified to a pH of approximately 4, at which point an orange oil formed. The aqueous mixture was stirred vigorously and additional acid was added to lower the pH to 2.5-3. The orange oil congealed into a granular solid, which was filtered, washed successively with water and 1N hydrochloric acid, and dried under vacuum at 50 °C to afford the title product as an off-white solid (130 g).

The reaction mixture was stirred at room temperature until gas evolution ceased (approximately 1.5 hours). The reaction mixture was concentrated in vacuo to provide the crude acid chloride as an oil that was used without further purification. The crude acid chloride was dissolved in acetonitrile (95 mL) and added to a solution of the benzoxazin-2, 4-dione prepared as in Step C in acetonitrile (95 mL). The resulting mixture was stirred at room temperature (approximately 30 minutes). Pyridine (95 mL) was added and the mixture heated to about 90 °C (approximately 1 hour). The reaction mixture was cooled to about 35 °C and isopropylamine (25 mL) was added. The reaction mixture exothermically warmed during the addition and then was maintained at about 50 °C (approximately 1 hour). The reaction mixture was then poured into ice water and stirred.

The resulting precipitate was collected by filtration, washed with water and dried in vacuo overnight to provide 37. 5 g of the title compound as a tan solid.

The hot reaction solution was poured onto a large excess of ice and 100 ml of ethyl acetate added almost immediately (before allowing all of the ice to melt). After stirring and allowing the remaining ice to melt, the ethyl acetate layer was separated, washed with water, aqueous saturated sodium bicarbonate and brine. Followed by drying over magnesium sulfate, the solvent was removed in vacuo to give a crude yellow oily solid residue.

The temperature rose to about 34 °C. 2-Chlorophenylhydrazine hydrochloride (90 g, 0.5 mole) was added portionwise over a period of 10 minutes to give a creamy suspension. The mixture was warmed to about 60 °C for about 45 minutes. The bulk of the acetic acid was removed by stripping on a rotary evaporator at a bath temperature of 65 °C. The remaining oily residue was added to about 800 ml of water with vigorous stirring and a heterogeneous mixture resulted. After about 15 minutes, dichloromethane (500 mL) was added and the mixture was partitioned. The aqueous phase was extracted with 300 ml of dichloromethane. The combined organic phases were washed with water and saturated sodium bicarbonate solution and then dried with MgS04 and filtered. Volatiles were removed on a rotary evaporator.

The crude product consisted of 151 g of a dark red oil, which contained approximately 89% of the desired product and 11% of the regioisomeric pyrazole (determined by NMR analysis).

Step 13 : Preparation of 1- (2-chlorophenyl)-3- vrazole-S- carboxylic acid A sample of the crude product from Step A (approximately 89%, 56.0 g, 0. 18 mole) was dissolved in acetonitrile (400 mL) and a solution of NaH2PO4 (120 g, 0.87 mole) in 520 mL of water was added. Sodium hypochlorite solution (5. 25% in water, 128 g, 2.6 mole) was added dropwise over 10-15 minutes. The orange solution was maintained at room temperature for 30 minutes. The reaction mixture was cooled in an ice bath and a solution of NaClO2 in 560 mL of water was added dropwise, keeping the temperature below 11 °C. Gas evolution was observed and an aqueous sodium hydroxide scrubber was used to quench evolved chlorine. After the addition was complete, the reaction mixture was kept cold for one hour then allowed to reach room temperature overnight. To the reaction mixture was added 80 mL of concentrated hydrochloric acid dropwise to bring the pH below 3. The reaction mixture was extracted twice with ethyl acetate and the combined organic extracts were added dropwise rapidly with stirring to a cooled (<15 °C) solution of 300 g of NAHSO3 in 1300 mL of water. The mixture was partitioned and the aqueous phase extracted with ethyl acetate. The combined organic phases were washed with saturated brine, dried (MgSO4), filtered and concentrated in vacuo. The residue was taken up in chlorobutane and reconcentrated (twice). The resulting brown solid was triturated in 100 mL of ethyl ether in hexane (1%). Small portions of chlorobutane were added to help granulate

the solid. The product was collected via filtration, washed with hexanes and dried. The product consisted of 40. 8 g of tan solid, which was essentially pure based upon 1H NMR.

The solution was treated with oxalyl chloride (15.7 mL, 0.18 mole), followed N-dimethylformamide (12 drops). Off-gassing began shortly after adding the N, N-dimethylformamide catalyst.

The reaction mixture was stirred for about 20 minutes under ambient conditions, then was heated to reflux for a period of 35 minutes. Volatiles were removed by concentrating the reaction mixture on a rotary evaporator at a bath temperature of 55 °C. The crude product, approximately 43 g of a light-yellow oil, was used directly in the next step.

The mixture was diluted with 350 mL of pyridine and heated to approximately 95 °C for a period of 2 hours. The mixture was cooled to 29 °C, then was treated with isopropylamine (32.2 mL, 0. 38 mole). The reaction mass self- heated to 60 °C and was maintained at about 50 °C for one hour, then stirred overnight. The reaction mixture was poured into 1 L of water and stirred. The resulting solid was collected by filtration and washed with water. The wet cake was taken up in a mixture of dichloromethane and methanol, the water removed, and the organic phase was dried with molecular sieves and filtered. Volatiles were removed on a rotary evaporator. The crude product was triturated with 1: 1 ether/hexane, collected by filtration and washed with hexanes to yield 42.6 g of a light tan solid melting at 230-231 °C.

Fonnulation/Utility Compounds used in accordance with this invention will generally be used as a formulation or composition with an agriculturally suitable carrier comprising at least one of a liquid diluent, a solid diluent or a surfactant. The formulation or composition ingredients are selected to be consistent with the physical properties of the active ingredient, mode of application and environmental factors such as soil type, moisture and temperature. Useful formulations include liquids such as solutions (including emulsifiable concentrates), suspensions, emulsions (including microemulsions and/or suspoemulsions) and the like which optionally can be thickened into gels. Useful formulations further include solids such as dusts, powders, granules, pellets, tablets, films, and the like which can be water- dispersible ("wettable") or water-soluble. Active ingredient can be (micro) -encapsulated and further formed into a suspension or solid formulation; alternatively the entire formulation of active ingredient can be encapsulated (or"overcoated"). Encapsulation can control or delay release of the active ingredient. Sprayable formulations can be extended in suitable media and used at spray volumes from about one to several hundred liters per hectare.

High-strength compositions are primarily used as intermediates for further formulation.

The formulations will typically contain effective amounts of active ingredient, diluent and surfactant within the following approximate ranges that add up to 100 percent by weight.

Thus, compositions of the present invention can further comprise a biologically effective amount of at least one additional invertebrate pest control compound or agent having a similar spectrum of control but a different mode of action. Contacting a plant genetically modified to express a plant protection compound (e. g. , protein) or the locus of the plant with a biologically effective amount of a compound of invention can also provide a broader spectrum of plant protection and be advantageous for resistance management.

Invertebrate pests are controlled in agronomic and nonagronomic applications by applying one or more of the compounds used in accordance with this invention, in an effective amount, to the environment of the pests including the agronomic and/or nonagronomic locus of infestation, to the area to be protected, or directly on the pests to be controlled. Thus, the present invention further comprises a method for the control of invertebrates in agronomic and/or nonagronomic applications, comprising contacting the invertebrates or their environment with a biologically effective amount of one or more of the compounds of the invention, or with a composition comprising at least one such compound or a composition comprising at least one such compound and an effective amount of at least one additional biologically active compound or agent. Examples of suitable compositions comprising a compound of the invention and an effective amount of at least one additional biologically active compound or agent include granular compositions wherein the additional biologically active compound is present on the same granule as the compound of the invention or on granules separate from those of the compound used in accordance with this invention.

A preferred method of contact is by spraying. Alternatively, a granular composition comprising a compound of the invention can be applied to the plant foliage or the soil.

Compounds used in accordance with this invention are also effectively delivered through plant uptake by contacting the plant with a composition comprising a compound used in accordance with this invention applied as a soil drench of a liquid formulation, a granular formulation to the soil, a nursery box treatment or a dip of transplants. Compounds are also effective by topical application of a composition comprising a compound used in accordance with this invention to the locus of infestation. Other methods of contact include application of a compound or a composition of the invention by direct and residual sprays, aerial sprays, gels, seed coatings, microencapsulations, systemic uptake, baits, eartags, boluses, foggers, fumigants, aerosols, dusts and many others. The compounds used in accordance with this invention may also be impregnated into materials for fabricating invertebrate control devices (e. g. insect netting).

The compounds used in accordance with this invention can be incorporated into baits that are consumed by the invertebrates or within devices such as traps and the like. Granules or baits comprising between 0.01-5% active ingredient, 0.05-10% moisture retaining agent (s) and 40-99% vegetable flour are effective in controlling soil insects at very low application rates, particularly at doses of active ingredient that are lethal by ingestion rather than by direct contact.

The compounds used in accordance with this invention can be applied in their pure state, but most often application will be of a formulation comprising one or more compounds with suitable carriers, diluents, and surfactants and possibly in combination with a food depending on the contemplated end use. A preferred method of application involves spraying a water dispersion or refined oil solution of the compounds. Combinations with spray oils, spray oil concentrations, spreader stickers, adjuvants, other solvents, and synergists such as piperonyl butoxide often enhance compound efficacy.

The rate of application required for effective control (i. e. "biologically effective amount") will depend on such factors as the species of invertebrate to be controlled, the pest's life cycle, life stage, its size, location, time of year, host crop or animal, feeding behavior, mating behavior, ambient moisture, temperature, and the like. Under normal circumstances, application rates of about 0. 01 to 2 kg of active ingredient per hectare are sufficient to control pests in agronomic ecosystems, but as little as 0. 0001 kg/hectare may be sufficient or as much as 8 kg/hectare may be required. For nonagronomic applications, effective use rates will range from about 1.0 to 50 mg/square meter but as little as 0.1 mg/square meter may be sufficient or as much as 150 mg/square meter may be required.

One skilled in the art can easily determine the biologically effective amount necessary for the desired level of invertebrate pest control.

The following Tests in the Biological Examples of the Invention demonstrate the efficacy of methods of the invention for protecting plants from specific invertebrate pests.
