TITLE HERBICIDAL BENZENE COMPOUNDS.

BACKGROUND OF THE INVENTION This invention relates to agriculturally suitable compositions of certain herbicidal benzene compounds and a method for their use as selective preemergent or postemergent herbicides for controlling the growth of undesired vegetation in crops such as rice. New compounds effective for controlling the growth of undesired vegetation are in constant demand. In the most common situation, such compounds are sought to selectively control the growth of weeds in useful crops such as cotton, rice, corn, wheat and soybeans, to name a few. Unchecked weed growth in such crops can cause significant losses, reducing profit to the farmer and increasing costs to the consumer. In other situations, herbicides are desired which will control all plant growth. There are many products commercially available for these purposes, but the search continues for products which are more effective, less costly and environmentally safe.

SUMMARY OF THE INVENTION This invention comprises agriculturally suitable compositions wherein the active compounds are the compounds of Formulas I and II, and their method-of-use as preemergent and/or postemergent herbicides or plant growth regulants.

DETAILED DESCRIPTION OF THE INVENTION The compounds of Formulae I and II can be readily prepared by one skilled in the art by using the reactions and techniques described in Schemes 1 to 17 below. Many of the compounds disclosed herein are known in the art or can be prepared by well known literature procedures.

In some of the schemes, compounds of Formulae I and II are represented by formulae with a floating R ³

substituent wherein R ³ is attached at the 4- and 5-position, respectively (see Formula A below) . The definitions of R ¹ -R ³¹ and X are the same as defined for Formulae I and II above.

4-R ³ = Formula I 5-R ³ = Formula II

In cases where the substituent of a starting material is not compatible with the reaction conditions described for any of the reaction schemes, it can be assumed that the substituent is converted to a protected form prior to the described reaction scheme and then deprotected after the reaction using commonly accepted protecting/ deprotecting techniques (as an example, see T. W. Greene and P. G. M. Wuts,

"Protective Groups in Organic Synthesis", 2nd Edition, John Wiley and Sons, Inc., New York, 1991) . Otherwise alternative approaches known to one skilled in the art are available. The compounds of this invention are made by the following processes. Introduction of R ¹

Scheme 1 illustrates the preparation of compound 1, a compound of Formula I or II wherein R ¹ =N0 ₂ . Many nitrobenzenes are commercially available or can be prepared by literature methods . A variety of methods are known in the literature, for example, see J. March, Advanced Organic Chemistry, 3rd Ed., John Wiley and Sons, New York (1985) and references cited therein.

Scheme 1

nitration

Anilines of Formula 2 can be prepared from nitro compounds of Formula 1 by reduction with tin II chloride (Scheme 2) . Processes of this type are well known in the literature. For example, see T. Ho and C. M. Hong, Synthesis 1974 45. The aniline of Formula 2 can be converted to the halobenzene of Formula 3 (W=C1, Br, or I) using the Sandmeyer reaction. Alternatively, the phenol of Formula 4 can be obtained from the aniline by preparation of the diazonium salt followed by hydrolysis. Methods of these types are described in Sandier S. R.; Karo W., Organic Functional Group Preparations, Academic: New York, (1983); Chapters 13 and 17.

Scheme 2

Compounds of Formulae I and II wherein R ¹ is OCH ₃ , OCHF ₂ or 0CF ₃ can be prepared by the methods illustrated in Scheme 3. h m

Phenols of Formula 4 can be treated with a methylating agent, such as iodomethane or methyl- sulfate, and a base such as potassium carbonate, potassium hydroxide, potassium hydride, potassium t-butoxide, sodium hydride, sodium hydroxide or sodium carbonate in an inert solvent such as N, N-dimethyl- formamide, benzene, toluene, xylene or tetrahydrofuran. The reaction temperature ranges from 0-140°C and reaction time is between 30 minutes and 200 hours.

Upon completion of the reaction, the reaction mixture is concentrated under reduced pressure. Water is then added to the residue and extracted with organic solvent. The organic extract is dried over sodium sulfate or magnesium sulfate and concentrated to provide the crude anisole of Formula 5.

The crude product can be further purified by crystallization, distillation and flash column- chromatography if needed.

Compounds of Formula 6 and 7 are prepared by treating the phenol of Formula 4 with chlorodi- fluoromethane or chlorotrifluoromethane, respectively,

under literature conditions (K. Morimoto, K. Makino, S. Yamamoto and G. Sakata, J. Heterocycl . Chem . , 1990, 27, 807 and Fuss A.; Koch v., Synthesis, 1990, 604 and 681-685) . Introduction of R ²

Benzonitriles of Formula 9 can be prepared from the corresponding halobenzenes of Formula 8 by treatment with potassium cyanide or cuprous cyanide (Scheme 4) . The halobenzene is dissolved or dispersed in a solvent such as N, N-dimethylformamide or N-methyl-2-pyrrolidone and treated with the cyanide salt at temperatures of 120-180°C for 1 to 24 hours. Aqueous work-up followed by purification by distillation, recrystallization, or column chromatography affords the desired material .

Scheme 4

Alternatively, benzonitriles of Formula 9 can be prepared from nitrobenzenes of Formula 10 as illustrated in Scheme 4. The nitrobenzene is reduced to the aniline of Formula 11 by hydrogenation or methods described above. The aniline of Formula 11 can then be converted to the benzonitrile by formation of the diazonium salt followed by treatment with cuprous cyanide (see Sandier S. R.; Karo W., Organic Functional

Group Preparations, Academic: New York, (1983); Chapters 13 and 17) .

The benzonitriles of Formula 9 can be converted to compounds of the present invention wherein R ² =C0 ₂ R ⁴ , C(X)NR ¹⁷ R ¹⁸ , C (halogen) =NOR ⁷ and C(S)OR ⁶ as illustrated in Scheme 5.

The cyano compound can be converted to the amide of Formula 10 according to Youngdale G. A.; Oglia T. F., J. Med. Chem . 1985, 28, 1790-96 using 30% aqueous hydrogen peroxide, methanol and sodium hydroxide or A. Katritzky; B. Pilarski and L. ϋrogdi, Synthesis 1989, 950 using 30% aqueous hydrogen peroxide, potassium carbonate and dimethylsulfoxide. In addition, the cyano group in compounds of Formula 9 can be converted to carboxylic acids of Formula 11 using about 5-20% aqueous base such as sodium hydroxide or potassium hydroxide (preferably 5%) at about 25 to 100°C for 1 to 24 hours. The carboxylic acid can be converted to the acid chloride of Formula 12 using thionylchloride or phosphorus oxychloride. The acid chloride may be treated with R ⁴ OH to provide the corresponding ester of Formula 13 under conditions well known to those versed in the art. In an analogous fashion the acid chloride may be treated with NHR ¹⁷ R ¹⁸ to provide the corresponding amide of Formula 14. The thioesters of Formula 15 and the thioamides of Formula 16 can be synthesized by treatment of the aforementioned esters and amides, respectively, with Lawesson\'s reagent (see Pedersen, B. S., Lawesson, S. O., Tetrahedron 1979, 2433-2437 and references cited therein) .

The compounds of Formula 17 can be prepared from the amides of Formula 14 (Scheme 6) . The amide is treated with a tetrahalomethane/triphenylphosphine reagent as described in the art (T. Sakamoto et al. , Synthesis, 1991, 9, 950-952 and E. C. Taylor et al. , J. Org. Chem . , 1971, 36, 253) .

The benzaldehyde of Formula 18 can be converted to the oxime of Formula 20 by reacting it with NH ₂ OR ⁷ . The aldehyde of Formula 18 can also be reacted with active methylene compounds of the type CH ₂ R ¹ R ²² and a base such as pyridine and potassium carbonate to provide the olefin of Formula 21. The secondary alcohol of Formula 22 (R ² =CH(C ₁ -C ₂ alkyl)OH) can be prepared by treatment of the benzaldehyde with (C ₁ -C ₂ alkyl)MgBr. Alcohols of Formulae I and II wherein R ² =CH ₂ OH can be prepared by conventional

reduction of benzaldehydes of Formula 18. These benzylic alcohols and the alcohols of Formula 22 can be treated with acetyl chloride or acetic anhydride under standard conditions to prepare compounds wherein R ²⁰ is C(0)CH ₃ .

The terminal alkyne of Formula 24 can be synthesized from the benzaldehyde of Formula 18 by the Corey-Fuchs homologation by treating the aldehyde first with carbon tetrabromide/triphenylphosphine to form the dibromoolefin of Formula 23, followed by treatment with n-butyllithium, rearrangement and quench with aqueous acid according to Corey, E. J., Fuchs, P. L., Tetrahedron Lett . 1972, 3769-3772 and references cited therein. Cyanooximes of Formula 26 wherein R ² = C(CN)=NOR ⁷ can be prepared as illustrated in Scheme 9. The phenylacetonitrile of Formula 25 is treated with an alkylnitrite under basic conditions using the procedures described in Noland, W. E., ed., Organic Syntheses VI, John Wiley: New York (1988), pp 199-203.

Treatment of the benzylic alcohol with a thionyl- halide (e . g . , thionylchloride) at 25-100°C in an inert solvent such as benzene, toluene or dichloromethane for

2-12 hours produces the halide of Formula 28. Displacement of the halide with a cyanide salt, for example potassium cyanide, produces the nitrile of Formula 29. This method is described in Sandier, S. R., Karo, W. in Organic Functional Group Preparations, Academic: New York (1983); Chapter 17. The nitrile can be converted to the amide of Formula 30 or the carboxylic acid of Formula 31 using conditions described above for the coversion of nitriles to amides and acids (see Scheme 5) . Introduction of R ³

In order for the nucleophilic aromatic substitution to occur, R ² must be a powerful electron-withdrawing substituent such as cyano or nitro. The halobenzenes of Formulae 23 and 24 are either commercially available or can be prepared by one skilled in the art using well known methods. h m

The reaction

temperature ranges from 0 to 140°C and reaction time is between 30 minutes and 120 hours.

Upon completion of the reaction, the reaction mixture is concentrated under reduced pressure. Water is then added to the residue and extracted with organic solvent. The organic extract is dried and concentrated to provide crude product. The crude phenylether of Formula 33 or 34 can be further purified by flash column chromatography if needed. In a similar fashion, R ¹³ SH and R ¹ R ¹⁵ NH can be used instead of R ¹² 0H or HO-N=CR ³⁰ R ³¹ in the process illustrated in Scheme 11 to afford compounds of Formula II wherein R ³ =R ¹³ S and R ¹⁴ R ¹⁵ N, respectively.

Compounds of Formula I wherein R ³ =OR ¹² can be synthesized as illustrated in Scheme 12. The anisoles of Formula 35 are commercially available or can be synthesized by one skilled in the art by following literature methods or slight modifications thereof. Alternatively, the phenols of Formula 36 can be prepared from the nitro compounds as described above (see Scheme 2) .

The complete demethylation of the methylether can be accomplished using boron tribromide (BBr ₃ ) or other

reagents described in a review by M. V. Bhatt and S. U. Kulkarni, Synthesis 1983, 248-282. The phenol then can be alkylated to produce the R ¹² ether of Formula 37. The thiols can be prepared using the well-known methods four step procedure for converting anilines to thiols illustrated in Scheme 13. These synthetic steps are described in detail in Sandier, S. R.; Karo, W., Organic Functional Group Preparations, Academic: New York (1983), Chapters 16, 13, 4 and 18, respectively.

Compositions of this invention comprising the active compounds of Formula I or II will generally be used in formulation with an agriculturally suitable carrier comprising a liquid or solid diluent or an organic solvent. Useful formulations may be in the form that includes dusts, granules, pellets, solutions, suspensions, emulsions, wettable powders, emulsifiable concentrates, dry flowables and the like, consistent 0 with the physical properties of the active ingredient, mode of application and environmental factors such as soil type, moisture and temperature. 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 which add up 100 weight percent.

Weight Percent

Typical solid diluents are described in Watkins, et al., Handbook of Insecticide Dust Diluents and

Carriers, 2nd Ed., Dorland Books, Caldwell, New Jersey. Typical liquid diluents and solvents are described in Marsden, Solvents Guide, 2nd Ed., Interscience, New York, 1950. McCutcheon \'s Detergents and Emulsifiers Annual, Allured Publ. Corp., Ridgewood, New Jersey, as well as Sisely and Wood, Encyclopedia of Surface Active Agents, Chemical Publ. Co., Inc., New York, 1964, list surfactants and recommended uses. All formulations can contain minor amounts of additives to reduce foam, caking, corrosion, microbiological growth, etc. Solutions are prepared by simply mixing the ingredients. Fine solid compositions are made by blending and, usually, grinding as in a hammer mill or fluid energy mill. Water-dispersible granules can be produced be agglomerating a fine powder composition; see for example, Cross et al., Pesticide Formulations,

Washington, D.C., 1988, pp 251-259. Suspensions are prepared by wet-milling; see, for example, U.S. 3,060,084. Granules and pellets can be made by spraying the active material upon preformed granular carriers or by agglomeration techniques. See Browning, "Agglomeration", Chemical Engineering, December 4, 1967, pp 147-48, Perry\'s Chemical Engineer \'s Handbook, 4th Ed., McGraw-Hill, New York, 1963, pages 8-57 and following, and WO 91/13546. Pellets can be prepared as described in U.S. 4,172,714. Water-dispersible and water-soluble granules can also be prepared as taught in DE 3,246,493.

For further information regarding the art of formulation, see U.S. 3,235,361, Col. 6, line 16 through Col. 7, line 19 and Examples 10-41; U.S.

3,309,192, Col. 5, line 43 through Col. 7, line 62 and Examples 8, 12, 15, 39, 41, 52, 53, 58, 132, 138-140, 162-164, 166, 167 and 169-182; U.S. 2,891,855, Col. 3, line 66 through Col. 5, line 17 and Examples 1-4; Klingman, IVeed Control as a Science, John Wiley and

Sons, Inc., New York, 1961, pp 81-96; and Hance et al., Weed Control Handbook, 8th Ed., Blackwell Scientific Publications, Oxford, 1989.

Tests results indicate that the compounds of the present invention are highly active preemergent and/or postemergent herbicides and/or plant growth regulants. Many of them have utility for broad-spectrum pre- and/or postemergence weed control in areas where complete control of all vegetation is desired such as around fuel storage tanks, industrial storage areas. parking lots, drive-in theaters, around billboards and highway and railroad structures. Some of the compounds are useful for the control of selected grass and broadleaf weeds with tolerance to important agronomic crops which include but are not limited to barley, cotton, wheat, corn, soybeans and rice. Those skilled in the art will appreciate that not all compounds are equally effective against all weeds. Alternatively, the subject compounds are useful to modify plant growt .

In certain instances, combinations with other herbicides having a similiar spectrum of control but a different mode of action will be particularly advantageous for resistance management. UTILITY

Test results indicate that compositions of this invention are herbicidally active postemergence and preemergence. The compositions of this invention are particularly useful for the control of barnyardgrass (Echinochloa crus-galli ) in crops especially upland and rice ( Oryza sativa) .

A herbicidal effective amount of the compounds of this invention is determined by a number of factors. These factors include: formulation selected, method of application, amount and type of vegetation present, growing conditions, etc. In general terms, a herbicidally effective amount is a rate from 0.005 to 10 kg/ha with a preferred rate range of 0.01 to 1 kg/ha. One skilled in the art can easily determine effective application rates for desired level of weed control.

The compositions of this invention may include as active compounds the compounds of Formulas I or II alone or in combination with other commercial herbicides, insecticides, or fungicides. The following list exemplifies some of the herbicides suitable for use in mixtures . A mixture of one or more of the following herbicides with a compound of this invention may be particularly useful for weed control.

At the same time, these crop and weed species were also treated postemergence with test chemicals. Plants ranged in height from two to eighteen cm and were in the two to three leaf stage for the postemergence treatment. Treated plants and untreated controls were maintained in a greenhouse for approximately eleven days, after which all treated plants were compared to untreated controls and visually evaluated for injury. Plant response ratings, summarized in Table B, are based on a 0 to 10 scale where 0 is no effect and 10 is complete control. A dash (-) response means no test results.

The test chemicals were formulated in a non- phytoxic solvent and applied to water that covered the soil surface (flood application) . Seeds of barnyardgrass (Echinochloa crus-galli) , and rice ( Oryza sativa) were planted in silt loam soil in separate containers. Containers of barnyardgrass and rice were grown for ten days (barnyardgrass at 2 leaf stage) and flooded one day prior to treatment. Water depth was maintained at approximately 2.5 cm for the duration of the test.

All plant species were grown using normal greenhouse practices. Treated plants were compared to untreated controls and visually evaluated eleven to fifteen days after treatment. Plant response ratings, summarized in Table C, were recorded on a 0 to 100 scale where 0 is no effect and 100 is complete control. A dash (-) response means no test result.
