The compounds of formula I can be prepared using processes known per se, for example described in WO 99/55693, for example by converting an isothiocyanate of formula 11 Q-N=C=S (11), wherein Q is as defined for formula 1, with a compound of formula I I I (in the form of the free base or in salt form) wherein Ro and no are as defined for formula I and Hal is halogen, especially chlorine, bromine or iodine, in an inert organic solvent, for example an ether, e. g. tetrahydrofuran (THF), at temperatures of from-10° to 30°C, preferably from 0° to 20°C, into the compound of formula IV treating that compound, in accordance with variant a), advantageously in a suitable solvent, for example an aromatic hydrocarbon, e. g. toluene or an isomer of xylene, or an ether, e. g. tetrahydrofuran, with a (thio-) carbonylating agent, e. g. (thio-) phosgene of formula Ila Cl2C (X) (Ila), wherein X is oxygen or sulfur, for example in the form of a 20 % solution of (thio-) phosgene in toluene, at from-10° to 30°C, preferably from 0° to 20°C, yielding the compound of formula V the radicals Q, X and Ro and no in the compounds of formulae IV and V being as defined, and then treating that compound in an inert organic solvent, for example an aromatic hydrocarbon, e. g. toluene or an isomer of xylene, with imidazole, with gentle heating at temperatures of from 40° to 80°C, preferably from 50° to 70°C, or treating the compound of formula IV, in accordance with variant b), advantageously in a suitable solvent, for example an aromatic hydrocarbon, e. g. toluene or an isomer of xylene, or an ether, e. g. tetrahydrofuran, with a (thio-) carbonylating agent, e. g.

The compounds of formula III in Reaction Scheme 1 are known and can be prepared, for example, as described in WO 99/47525.

The compounds of formula IV in Reaction Scheme 1 are new. Those compounds of formula IV, wherein Ro, no and Q are as defined for formula 1, constitute important intermediates for the synthesis of compounds of formula I and the invention relates also thereto.

The reactions to give compounds of formula I are advantageously carried out in aprotic inert organic solvents. 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 acetonitrile or propionitrile, amides such as N, N-dimethylformamide, diethylformamide or N-methylpyrrolidinone. The reaction temperatures are preferably between-20°C and +120°C. In general, the reactions are slightly exothermic and, as a rule, they can be carried out at room temperature. To shorten the reaction time, or else to start the reaction, the mixture may be heated briefly to the boiling point of the reaction mixture. The reaction times can also be shortened by adding a few drops of base as reaction catalyst. Suitable bases are especially tertiary amines such as trimethylamine, triethylamine, quinuclidine, 1,4-diazabicyclo [2.2.2octane, 1,5-diazabicyclo [4.3.0] non-5-ene or 1,5-diazabicyclo- [5.4.0] undec-7-ene. However, inorganic bases such as hydrides, e. g. sodium hydride or calcium hydride, hydroxides, e. g. sodium hydroxide or potassium hydroxide, carbonates such as sodium carbonate and potassium carbonate, or hydrogen carbonates such as potassium hydrogen carbonate and sodium hydrogen carbonate, may also be used as bases.

The compounds of formula I can be isolated in customary manner by concentrating and/or by evaporating the solvent and 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 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 desired, 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 can be used as herbicides in unmodified form, that is to say as they are obtained in 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, 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.

The formulations, that is to say the compositions, preparations or mixtures comprising the compound of formula I or at least one compound of formula I and, generally, one or more solid or liquid formulation adjuvants, are prepared in known manner, for example by homogeneously mixing and/or grinding the active ingredients with the formulation adjuvants, for example solvents or solid carriers. Furthermore, surface-active compounds (surfactants) may also 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 compound of formula I being formulated, suitable surface- active compounds are non-ionic, cationic and/or anionic surfactants and mixtures of surfactants 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. Furthermore, the surfactants customarily employed in formulation technology, which are described, inter alia, in"Mc Cutcheon's Detergents and Emulsifiers Annual"MC Publishing Corp., Ridgewood New Jersey, 1981, Stache, H., "Tensid-Taschenbuch", Carl Hanser Verlag, MunichNienna, 1981 and M. and J. Ash, "Encyclopedia of Surfactants", Vol 1-111, Chemical Publishing Co., New York, 1980-81, are also suitable for preparation of the herbicidal compositions according to the invention.

The herbicidal formulations generally comprise 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), antifoams, for example silicone oil, preservatives, viscosity regulators, binders and tackifiers, as well as fertilisers or other active ingredients.

The compounds of formula I are generally applied to the plant or to 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 in cereals, cotton, soybeans, sugar beet, sugar cane, plantation crops, rape, maize and rice, and also for non-selective weed control. Crops are to be understood as including also crops that have been made tolerant to herbicides or classes of herbicides by means of conventional plant breeding or by genetic engineering methods. The weeds to be controlled may be either monocotyledonous or dicotyledonous weeds, for example Stellaria, Nasturtium, Agrostis, Digitaria, Avena, Setaria, Sinapis, Lolium, Panicum, Solanum, Echinochloa, Scirpus, Monochoria, Sagittaria, Bromus, Alopecurus, Sorghum halepense, Rottboellia, Cyperus, Abutilon, Sida, Xanthium, Amaranthus, Chenopodium, Ipomoea, Chrysanthemum, Galium, Viola and Veronica.
