J. Am. Chem. Soc. 1999, 121, 1473). Starting from VIII by means of analogous Pd(O) cross-couplings, there are obtainable malonodinitriles IX, from which amides V are obtainable.

The reaction is preferably carried out under an inert gas atmosphere. The compounds of formula XXX are known or can be prepared according to known processes, as described, for example, in J. Chem. Soc. Perkin Trans. 1 (1987), (4), 877-884.

Hannaford, P.W.G. Smith, A.R. Tatchell; Longman Scientific & Technical 1989, page 923. The compounds of formula VI are known, some of them are commercially available or they can be prepared analogously to known compounds. Suitable for that reaction are bases, such as tri-alkali metal phosphates, alkali metal and alkaline earth metal hydrides, alkali metal and alkaline earth metal amides or alkali metal alcoholates, for example tripotassium phosphate, sodium hydride, lithium diisopropylamide (LDA), sodium tert-butanolate or potassium tert-butanolate. Special preference is given to sodium tert-butanolate, potassium tert-butanolate and tripotassium phosphate. Suitable solvents are, for example, aromatic hydrocarbons, such as xylene or toluene, ethers, such as tetrahydrofuran, dioxane or ethylene glycol dimethyl ether, dimethyl sulfoxide or tertiary amides, such as dimethylformamide, N-methylpyrrolidinone or dimethylacetamide or acyclic ureas, such as N,N'-dimethylpropyleneurea. The palladium catalysts suitable for the C-C linkage reaction of a compound of formula XXX with a compound of formula VIII are generally palladium(II) or palladium(O) complexes, such as palladium(II) dihalides, palladium(lI) acetate, palladium(II) sulfate, bis(triphenyl phosphine)palladium(lI) dichloride, bis(tricyclopentylphosphine)palladium(II) dichloride, bis(tricyclohexylphosphine)palladium (II) dichloride, bis(dibenzylideneacetone)palladium (0) or tetrakis(triphenylphosphine)palladium(0). The palladium catalyst can also be prepared from palladium(lI) or palladium(0) compounds by complexing with the desired ligands in situ, for example by placing the palladium(lI) salt to be complexed, for example palladium(II) dichloride (PdCl 2 ) or palladium(ll) acetate (Pd(OAc) 2 ), together with the desired ligand, for -13 example triphenylphosphine (PPh 3 ), tricyclopentylphosphine or tricyclohexylphosphine, together with the selected solvent, a compound of formula VIII, a compound of formula XXX and base. Bidendate ligands are also suitable, for example 1,1'-bis(diphenylphosphino) ferrocene or 1,2-bis(diphenylphosphino)ethane. By heating the reaction mixture, the palladium(Il) or palladium(0) complex desired for the C-C coupling reaction is formed in situ, and said complex then initiates the C-C coupling reaction. The palladium catalysts are used in an amount of from 0.001 to 50 mol %, preferably in an amount of from 0.1 to 15 mol %, based on the compound of formula VIII. The reaction temperatures are selected in dependence upon the solvent used and, where applicable, the pressure. The reaction is preferably carried out at atmospheric pressure. A further synthesis variant involves the ortho-functionalisation of a bi-aromatic compound: in that process, it is to be noted that any ortho-position CH 2 that is present must be protected against competitive metallisation before the introduction of the second ortho substituent (R 3 ). o ci r 0 N O N, 0 0 TMEDA, s-BuU diethylamine THF, R 1

A preferred hydrohalic acid is hydrochloric acid. The substituent G can be introduced by the reaction of compounds of type I with organic or inorganic acids under water-removing conditions or in the presence of a coupling reagent. Acid chlorides and acid anhydrides are also very suitable for that purpose. It is to be noted that, in dependence on the type of substituents R 1 , R 3 , R 4 and R. - Rj,, the compound of -17 formula I may be in the form of a geometric and/or optical isomeric mixture or in the form of a tautomeric mixture.

Such solvents are hydrocarbons, such as benzene, toluene, xylene or cyclohexane, chlorinated hydrocarbons, such as dichloromethane, trichloromethane, tetrachloromethane or chlorobenzene, ethers, such as diethyl ether, ethylene glycol dimethyl ether, diethylene glycol dimethyl ether, tetrahydrofuran or dioxane, nitriles, such as -18 acetonitrile or propionitrile, amides, such as N,N-dimethylformamide, diethylformamide or N methylpyrrolidinone. The reaction temperatures are preferably from -20*C to +1 20*C. The reactions are generally slightly exothermic and can usually be carried out at room temperature. To reduce the reaction time or to initiate the reaction, the reaction mixture may also optionally be heated to boiling point for a short time. The reaction times can also be shortened by the addition of a few drops of base as reaction catalyst. Suitable bases are especially tertiary amines, such as trimethylamine, triethylamine, quinuclidine, 1,4-diaza bicyclo[2.2.2]octane, 1,5-diazabicyclo[4.3.0]non-5-ene or 1,5-diazabicyclo[5.4.0]undec-7 ene. As bases it is also possible, however, to use inorganic bases, e.g. hydrides, such as sodium or calcium hydride, hydroxides, such as sodium or potassium hydroxide, carbonates, such as sodium and potassium carbonate, or hydrogen carbonates, such as potassium and sodium hydrogen carbonate. The compounds of formula I can be isolated in customary manner by concentration and/or evaporation of the solvent and can be purified by recrystallisation or trituration of the solid residue in solvents in which they are not readily soluble, such as ethers, aromatic hydrocarbons or chlorinated hydrocarbons. For the use of the compounds of formula I according to the invention or compositions comprising them, there are suitable any of the methods of application customary in agriculture, such as preemergence application, postemergence application and seed dressing, as well as various methods and techniques, such as the controlled release of active ingredient. In that method the active ingredient is applied in solution to mineral granule carriers or polymerised granules (urea/formaldehyde) and dried. Where appropriate, 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. The compounds of formula I can be used as herbicides in unmodified form, i.e. as obtained during synthesis, but are preferably formulated in customary manner together with the adjuvants conventionally employed in formulation technology, e.g. into emulsifiable concentrates, directly sprayable or dilutable solutions, dilute emulsions, wettable powders, soluble powders, dusts, granules and microcapsules. Such formulations are described, for example, in WO 97/34485 on pages 9 to 13. 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.
-19 The formulations, i.e. the compositions, preparations or mixtures comprising the active ingredient of formula I or at least one active ingredient of formula I and generally one or more solid or liquid formulation adjuvants, are prepared in known manner, e.g. by intimately mixing and/or grinding the active ingredients with the formulation adjuvants, e.g. solvents or solid carriers. Surface-active compounds (surfactants) may additionally be used in the preparation of the formulations. Examples of solvents and solid carriers are given, for example, in WO 97/34485 on page 6. Depending on the nature of the active ingredient 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, in WO 97/34485 on pages 7 and 8. The surfactants customarily employed in formulation technology, which are described inter a/ia in "Mc Cutcheon'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 I-Ill, Chemical Publishing Co., New York, 1980-81, are also suitable for the preparation of the herbicidal compositions according to the invention. The herbicidal formulations usually comprise from 0.1 to 99 % by weight, especially from 0.1 to 95 % by weight, 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 are preferably formulated as concentrates, the end user will normally employ dilute formulations. The compositions may also comprise further ingredients such as stabilisers, e.g. vegetable oils and epoxidised vegetable oils (epoxidised coconut oil, rapeseed oil or soybean oil), antifoams, e.g. silicone oil, preservatives, viscosity regulators, binders, tackifiers, as well as fertilisers or other active ingredients. The active ingredients of formula I are generally used on the plant or on 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 - 20 dependent upon the type of action, the stage of development of the crop plant and of the weed, and also upon the application (place, time, method) and, in dependence on those parameters, can vary within wide ranges. The compounds of formula I are distinguished by herbicidal and growth-inhibiting properties that make them suitable for use in crops of useful plants, especially in cereals, cotton, soybeans, sugar beet, sugar cane, plantation crops, rape, maize and rice, and for non selective weed control. Crops are also to be understood as being those which have been rendered tolerant to herbicides or classes of herbicide by conventional methods of breeding or by genetic engineering techniques, e.g. IMI Maize, Poast Protected Maize, Liberty Link Maize, B.t./Liberty Link Maize, IMI/Liberty Link Maize, IMI/Liberty Link/B.t. Maize, Roundup Ready Maize and Roundup Ready/B.t. Maize. The weeds to be controlled may be either monocotyledonous or dicotyledonous weeds, for example Stellaria, Nasturtium, Agrostis, Digitaria, Avena, Setaria, Sinapis, Lolium, Solanum, Echinochloa, Scirpus, Monochoria, Sagittaria, Bromus, Alopecurus, Sorghum halepense, Rottboellia, Cyperus, Abutilon, Sida, Xanthium, Amaranthus, Chenopodium, lpomoea, Chrysanthemum, Galium, Viola and Veronica. The compound of formula I can be mixed advantageously with a number of further known herbicides, preferably selected from the groups of sulfonylureas, ureas, chloroacetanilides, chloroacetamides, diphenyl ethers, nitroanilines, oxadiazolones, pyrazoles, triazines, (hetero)aryloxypropionic acids, carbamates, thiocarbamates, thiatriazines, cyclohexane diones, imidazolinones, triazolopyrimidinesulfonamides, pyrimidinyloxypyridinecarboxylic acids and pyrimidinyloxybenzoic acids. As a result, for example, a substantial widening of the weed spectrum and in many cases also an increase in selectivity towards the useful plants is obtained. The mixing partners of the compound of formula I may also optionally be present in the form of esters or salts, as mentioned, for example, in The Pesticide Manual, Eleventh Edition, 1997, BCPC. The compound of formula I and mixtures thereof with the further herbicides mentioned above can also be used in combination with safeners.

Ph = phenyl Example B2: Postemergence herbicidal action Monocotyledonous and dicotyledonous test plants are sown in standard soil in pots. At the 2 to 3-leaf stage of the test plants, an aqueous suspension (prepared from a wettable powder (Example F3, b) according to WO 97/34485) of the test compound or an emulsion (prepared from an emulsifiable concentrate (Example F1, c) according to WO 97/34485) of the test compound is applied by spraying at an optimum concentration (500 litres of water/ha). The test plants are then cultivated further in a greenhouse under optimum conditions. After a test duration of from 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.
