Gribble, Pergamon 2000, Tetrahedron Lett.

1986 (27), 1171; Tetrahedron Organic Chemistry 2000 (20), 359-362; ibid. 2000 (20), 390- 394; and K. Sonogashira in Comprehensive Organic Synthesis, Editors 1. Fleming et al, Oxford 1991, Vol. 3, page 521 ff. , for example by reacting a compound of formula Ila wherein Ri and n are as defined for formula I (Q = Q1) and X is halogen, with a compound of formula Illa wherein R3 and R4 are as defined for formula) and M+ is an alkali metal cation such as, for example, a lithium, sodium or potassium cation, to form a compound of formula IVa wherein Ri, R3, R4 and n are as defined for formula 1, and then coupling that compound with a compound of formula V wherein Z, R2 and m are as defined for formula I and A is a leaving group such as, for example, halogen or trifluoromethanesulfonate, in the presence of a palladium catalyst.

Preparation of the compounds of formula I wherein Q is a group Q2, that is to say compounds of formula Ib wherein Q is a group Q3, that is to say compounds of formula Ic (tic) ; wherein Q is a group Q4, that is to say compounds of formula Id wherein Q is a group Q5, that is to say compounds of formula le (le) ; and wherein Q is a group Q6, that is to say compounds of formula If (If), is carried out in a manner analogous to that described above by way of example for the compounds of formula la (Q = Qi).

These preparation procedures for the compounds of formula I are illustrated in Reaction Schemes 1,2 and 3 specifically using the example of the compound of formula la (Q = Q1).

It is generally true of all three Reaction Schemes that the various substituents R1 and R2 in the compounds of formulae Ila and V either are already present at the outset or, however, they may be successively introduced only later in the reaction sequence, for example by means of nucleophilic or electrophilic aromatic substitution.

The same is also true of the analogous preparation of compounds of formulae lb, Ic, Id, le and If (Q is a group Q2 to Q6), starting from the respective compounds of formulae llb, llc, lid, tie and Ilf : In accordance with Reaction Scheme 1, the compounds of formula la can be obtained, for example, by reaction of substituted propargyl ethers of formula IVa with compounds of formula V by means of Sonogashira coupling.

The propargyl ethers of formula IVa can, for their part, be obtained by a nucleophilic aromatic substitution reaction of compounds of formula Ila wherein X is halogen with alcoholates of formula Illa. Such substitution reactions are standard methods and may be carried out, for example, in analogy to Tetrahedron 1972 (28), 4155; Heterocycles 1990 (31), 1275 (for Q = Ql) ; J. Org. Chem. 1961 (26), 2764 (for Q = Q2) ; Tetrahedron Lett. 1996 (37), 4065; Heterocyclic Chem. 1995 (32), 1057 (for Q = Q3) ; J. Am. Chem. Soc. 1951 (73), 2986 (for Q = Q4) ; Collect Czech. Chem. 1975 (40), 2680 (for Q = Q5) ; and Tetrahedron Lett. 1985 (26), 4355 (for Q = Q6).

In the next step, the propargyl ethers of formula Va are coupled with substituted phenyl or pyridine derivatives of formula V (Z is =N-or =C (R2) -) under typical Sonogashira conditions (K. Sonogashira in Comprehensive Organic Synthesis 1991, Vol. 3, page 521 ff.; J. Org. Chem. 1998 (63), 8551-8553). Suitable catalyst mixtures are, for example, tetrakis (triphenylphosphine) palladium or bis (triphenylphosphine) palladium (II) dichloride together with copper (l) iodide (Cul) ; suitable bases are preferably amines, for example triethylamine, diethylamine or diisopropylethylamine.

The phenyl or pyridine derivatives of formula V preferably have a leaving group A, A being, for example, halogen or trifluoromethanesulfonate (Tetrahedron Organic Chemistry 2000 (20), 209-213; J. Org. Chem. 1998 (63), 8551-8553) and Tetrahedron Lett. 1986 (27), 1171.

Solvents used for the Sonogashira reaction are usually ethers, for example tetrahydrofuran, chlorinated hydrocarbons, for example chloroform, or dipolar aprotic solvents, for example dimethylformamide or dimethyl sulfoxide, and also amines, for example triethylamine or piperidine.

Sonogashira, as shown in diagrammatic form in Reaction Scheme 2, results in compounds of formula VII.

Such reactions are documented, for example, in Tetrahedron Organic Chemistry 2000 (20), 209-213 for pyridine derivatives and in J. Org. Chem. 1988 (53), 386; ibid. 1998 (63), 8551- 8553; and Tetrahedron Lett. 1986 (27), 1171 for phenyl derivatives. Subsequent reaction of the propargyl alcohols of formula VII with pyrazine derivatives of formula Ila wherein X is halogen yields the compounds of formula la (Q = Qi).

The other compounds of formula I wherein Q is a group Q2, Q3, Q4, Q5 or Q6 can also be prepared in a manner analogous to that shown in Reaction Scheme 2.

X=OH 0 > Cul, base _x 4 VIII : Xi = halogen, OTs, OMs la Activation of the alcohol of formula VII according to Reaction Scheme 3 is carried out, for example, by sulfonylation or halogenation.

Sulfonylation of the alcohol of formula VII is a standard reaction and can be carried out, for example, using a sulfonic acid chloride, for example mesyl chloride or para-toluenesulfonic acid chloride (p-TosCI), in the presence of a tertiary amine, e. g. triethylamine, or an aromatic amine, e. g. pyridine, in a solvent such as, for example, a chlorinated hydrocarbon, e. g. carbon tetrachloride or methylene chloride, or an amine, e. g. pyridine. Such reactions are generally known and are described, for example, in J. Org. Chem. 1997 (62), 8987; J.

Het. Chem. 1995 (32), 875-882; and Tetrahedron Lett. 1997 (38), 8671-8674.

Halogenation of the alcohol of formula VII can be carried out in analogy to standard methods. For example, bromination can be successfully carried out using carbon tetrabromide in the presence of triphenylphosphine (Synthesis 1998,1015-1018) in methylene chloride. Chlorination can be successfully carried out using mineral acids, for example using concentrated hydrochloric acid (J. Org. Chem. 1955 (20), 95), or using para- toluenesulfonic acid chloride in the presence of an amine, for example triethylamine, in a solvent, for example methylene chloride (Tetrahedron Lett. 1984 (25), 2295).

Preparation of the compound of formula la according to Reaction Scheme 3 can be carried out analogously to Synthesis 1995,707-712 and Tetrahedron Lett. 1994 (35), 6405-6408, for example by means of copper iodide-catalysed etherification of the hydroxy-pyrazine of formula Ila in the presence of the tosylat (Xi = OTs) or mesylate (Xi = OMs) or halide (Xi = halogen) of formula VIII. Suitable solvents are dimethylformamide or acetonitrile ; suitable bases are preferably potassium carbonate or 1, 8-diazabicylo [5.4. 0] undec-7-ene (DBU). The etherification can also be carried out in halogenated or aromatic hydrocarbons as solvent, for example in chloroform or in benzene, in the presence of silver carbonate as base. Such selective O-alkylation reactions in the presence of a ring nitrogen atom are described, for example, in Synth. Commun. 1994 (24), 1367 and Heterocycles 1990 (31), 819.

A further method by which the compounds of formula I can be prepared is performed with the aid of the Mitsunobu reaction in a manner analogous to that described, for example, in Synthesis 1981 (1); Tetrahedron Lett. 35,2819-2822 (1994); and Chem. Letters 1994,539 (with TMAD reagent as a replacement for the DEAD in the two aforesaid references). This synthesis route is illustrated in Reaction Scheme 4 using the example of the compounds of formula la (pyrazinyloxy-alkyne derivatives). Reaction Scheme 4 Mitsunobu : (Rz) m Z Ruz / R Z 4 R 3 vn N Vil R nN Vl I R R \ J| v >/4 PPh3, DEAD, solvent e. g. THF n Ifa : X=OH ta The following applies to the individual reaction steps according to Reaction Schemes 1 to 4: The reactions resulting in the compounds of formula I are advantageously performed in aprotic, inert, organic solvents. Such solvents are hydrocarbons, such as benzene, toluene, xylene or cyclohexane, chlorinated hydrocarbons, such as dichloromethane, trichloro- methane, tetrachloromethane or chlorobenzene, ethers, such as diethyl ether, ethylene glycol dimethyl ether, diethylene glycol dimethyl ether, tetrahydrofuran or dioxane, nitriles, such as acetonitrile or propionitrile, amides, such as N, N-dimethylformamide, diethyl- formamide or N-methylpyrrolidinone. The reaction temperatures are preferably from-20°C to +120°C. The reactions are generally slightly exothermic and can usually be carried out at room temperature. For reducing the reaction time or also for initiation of the reaction, heating, up to the boiling point of the reaction mixture, may, where appropriate, be carried out for a short time. It is also possible for the reaction times to be reduced by adding a few drops of base as reaction catalyst. Suitable bases are especially tertiary amines, such as trimethylamine, triethylamine, quinuclidine, 1, 4-diazabicyclo [2.2. 2] octane, 1,5-diaza- bicyclo [4.3. 0] non-5-ene or 1, 5-diazabicyclo [5.4. 0] undec-7-ene. However, there may also be used as bases inorganic bases, such as hydrides, e. g. sodium hydride or calcium hydride, hydroxides, e. g. sodium hydroxide or potassium hydroxide, carbonates, e. g. sodium carbonate or potassium carbonate, or hydrogen carbonates, e. g. potassium hydrogen carbonate or sodium hydrogen carbonate.

The compounds of formula I may, in conventional manner, be isolated by concentrating and/or evaporating off the solvent and purified by recrystallising or triturating the solid residue in solvents in which they are not readily soluble, such as ethers, aromatic hydrocarbons or chlorinated hydrocarbons.

The starting compounds of formula Ila used in Reaction Schemes 1,2 and 3, and the corresponding starting compounds of formulae llb, llc, lid, lie and llf for preparation of the compounds of formulae Ib, Ic, Id, le and If are for the most part known or they can be prepared in analogy to known methods as described, for example, in J. Org. Chem. 1997 (62), 9112; ibid. 1958 (23), 1522; J. Chem. Soc. 1948,2191 ; Bull. Soc. Chim. Fr. 1957, 1009; J. Am. Chem. Soc. 74,1580-1582 (1952); US-A-5 547 919; J. Chem. Soc. 1960, 4590; J. Org. Chem. 1963 (28), 1682 ; J. Heterocycl. Chem. 1994 (31), 1177; and ibid 1982 (19), 1061.

The starting compounds of formulae III and Illa are likewise known and in some cases are commercially available, or they can be prepared in analogy to known methods.

The compounds of formula V are likewise known and in some cases are commercially available. Examples of substituted compounds of formula V wherein Z is =N-are described, for example, in Tetrahedron Organic Chemistry 20,209 (2000).

The compounds of formulae IV (and IVa to IVf) and VII are novel. The present invention accordingly relates also to those compounds.

For the use according to the invention of the compounds of formula 1, or of compositions comprising them, there come into consideration all methods of application customary in agriculture, for example pre-emergence application, post-emergence application and seed dressing, and also various methods and techniques such as, for example, the controlled release of active ingredient. For that purpose a solution of the active ingredient is applied to mineral granule carriers or polymerised granules (urea/formaldehyde) and dried. If required, it is also possible to apply a coating (coated granules), which allows the active ingredient to be released in metered amounts over a specific period of time.

The compounds of formula I may be used as herbicides in their unmodified form, that is to say as obtained in the synthesis, but they are preferably formulated in customary manner together with the adjuvants conventionally employed in formulation technology, for example into emulsifiable concentrates, directly sprayable or dilutable solutions, dilute emulsions, wettable powders, soluble powders, dusts, granules or microcapsules. Such formulations are described, for example, on pages 9 to 13 of WO 97/34485. As with the nature of the compositions, the methods of application, such as spraying, atomising, dusting, wetting, scattering or pouring, are chosen in accordance with the intended objectives and the prevailing circumstances.

The formulations, that is to say the compositions, preparations or mixtures comprising the compound (active ingredient) of formula 1, or at least one compound of formula 1, and, usually, one or more solid or liquid formulation adjuvants, are prepared in known manner, e. g. by homogeneously mixing and/or grinding the active ingredient (s) with the formulation adjuvants, for example solvents or solid carriers. Surface-active compounds (surfactants) may also be used in addition in the preparation of the formulations. Examples of solvents and solid carriers are given, for example, on page 6 of WO 97/34485.

Depending upon the nature of the compound of formula I to be formulated, suitable surface- active compounds are non-ionic, cationic and/or anionic surfactants and surfactant mixtures having good emulsifying, dispersing and wetting properties. Examples of suitable anionic, non-ionic and cationic surfactants are listed, for example, on pages 7 and 8 of WO 97/34485. In addition, the surfactants conventionally employed in formulation technology, which are described, inter alia, in"McCutcheon's Detergents and Emulsifiers Annual"MC Publishing Corp. , Ridgewood New Jersey, 1981, Stache, H.,"Tensid- Taschenbuch", Carl Hanser Verlag, Munich/Vienna, 1981, and M. and J. Ash, "Encyclopedia of Surfactants", Vol. 1-111, Chemical Publishing Co. , New York, 1980-81, are also suitable for the preparation of the herbicidal compositions according to the invention.

The herbicidal formulations generally contain from 0. 1 to 99 % by weight, especially from 0.1 to 95 % by weight, of herbicide, from 1 to 99.9 % by weight, especially from 5 to 99.8 % by weight, of a solid or liquid formulation adjuvant, and from 0 to 25 % by weight, especially from 0.1 to 25 % by weight, of a surfactant. Whereas commercial products will preferably be formulated as concentrates, the end user will normally employ dilute formulations. The compositions may also comprise further ingredients, such as stabilisers, for example vegetable oils or epoxidised vegetable oils (epoxidised coconut oil, rapeseed oil or soybean oil), anti-foams, for example silicone oil, preservatives, viscosity regulators, binders, tackifiers, and also fertilisers or other active ingredients.

The compounds of formula I are generally applied to the plant or the locus thereof at rates of application of from 0.001 to 4 kg/ha, especially from 0.005 to 2 kg/ha. The concentration required to achieve the desired effect can be determined by experiment. It is dependent on the nature of the action, the stage of development of the cultivated plant and of the weed and on the application (place, time, method) and may vary within wide limits as a function of those parameters.

The compounds of formula I are distinguished by herbicidal and growth-inhibiting properties, allowing them to be used in crops of useful plants, especially cereals, cotton, soybeans, sugar beet, sugar cane, plantation crops, rape, maize and rice, and also for non-selective weed control. The term"crops"is to be understood as including also crops that have been made tolerant to herbicides or classes of herbicides as a result of conventional methods of breeding or genetic engineering techniques. The weeds to be controlled may be either monocotyledonous or dicotyledonous weeds, such as, for example, Stellaria, Nasturtium, Agrostis, Digitaria, Avena, Setaria, Panicum, Sinapis, Lolium, Solanum, Echinochloa, Scirpus, Euphorbia, Monochoria, Sagittaria, Bromus, Alopecurus, Sorghum halepense, Rottboellia, Cyperus, Abutilon, Sida, Xanthium, Amaranthus, Chenopodium, Ipomoea, Chrysanthemum, Galium, Viola and Veronica.

Immediately after sowing, the test compounds, in the form of an aqueous suspension (prepared from a wettable powder (Example F3, b) according to WO 97/34485) or in the form of an emulsion (prepared from an emulsifiable concentrate (Example F1, c) according to WO 97/34485), are applied by spraying, in an optimum concentration (500 litres of water per ha). The test plants are then grown in a greenhouse under optimum conditions.

After a test duration of 4 weeks, the test is evaluated in accordance with a scale of nine ratings (1 = total damage, 9 = no action). Ratings of from 1 to 4 (especially from 1 to 3) indicate good to very good herbicidal action.

Test plants : Panicum (Pani), Digitaria (Digit), Euphorbia (Euph), Sida, Abutilon (Abut), Amaranthus (Amar), Chenopodium (Cheno), Stellaria (tell).

Example B2: Post-emergence herbicidal action Monocotyledonous and dicotyledonous test plants are sown in standard soil in pots. When the test plants are at the 2-to 3-leaf stage, the test compounds, in the form of an aqueous suspension (prepared from a wettable powder (Example F3, b) according to WO 97/34485) or in the form of an emulsion (prepared from an emulsifiable concentrate (Example F1, c) according to WO 97/34485), are applied by spraying, in an optimum concentration (500 litres of water per ha). The test plants are then grown on in a greenhouse under optimum conditions.

After a test duration of 2 to 3 weeks, the test is evaluated in accordance with a scale of nine ratings (1 = total damage, 9 = no action). Ratings of from 1 to 4 (especially from 1 to 3) indicate good to very good herbicidal action.

Test plants : Panicum (Pani), Euphorbia (Euph), Abutilon (Abut), Amaranthus (Amara), Stellaria (Stell), Veronica (Vero).
