ABSTRACT:

The invention relates to novel substituted sulphonylamino(thio)carbonyl compounds, to a plurality ofprocesses and novel intermediates for their preparation and to their use as herbicides.
It is already known that certain sulphonylaminocarbonyl compounds such as, for example, the compounds N-(2-chloro-6-methoxycarbonyl-phenylsulphonyl)-5-phenyl-1,2,4-oxadiazole-3-carboxamide (cf. EP 569810, Example 204), N-(2-chloro-6-methoxycarbonyl-phenylsulphonyl)-oxazole-2-carboxamide (cf. EP 569810, Example 239), N-(2-chloro-6-methoxycarbonyl-phenylsulphonyl)-4-methyl-oxazole-2-carboxamide (cf. EP 569810, Example 278), N-(2-chloro-6-methoxycarbonyl-phenylsulphonyl)-4-ethyl-5-methyl-oxazole-2-carboxamide (cf. EP 569810, Example 329), N-(2-chloro-6-methoxycarbonyl-phenylsulphonyl)-5-ethyl-oxazole-4-carboxamide (cf. EP 569810, Example 366), N-(2-chloro-6-methoxycarbonyl-phenylsulphonyl)-5-ethyl-thiazole-2-carboxamide (cf. EP 569810, Example 441), N-(2-chloro-6-methoxycarbonyl-phenylsulphonyl)-5-methyl-4-methylthio-thiazole-2-carboxamide (cf. EP 569810, Example 532), N-(2-chloro-6-methoxycarbonyl-phenylsulphonyl)-2,5-dimethyl-thiazole-4-carboxamide (cf. EP 569810, Example 576), N-(2-chloro-6-methoxycarbonyl-phenylsulphonyl)-2-chloro-thiazole-5-carboxamide (cf. EP 569810, Example 607), N-(2-chloro-6-methoxy-carbonyl-phenylsulphonyl)-1,3,4-oxadiazole-2-carboxamide (cf. EP 569810, Example 641), N-(2-chloro-6-methoxycarbonyl-phenylsulphonyl)-1,3,4-thiadiazole-2-carboxamide (cf. EP 569810, Example 701), N-(2-chloro-6-methoxycarbonyl-phenylsulphonyl)-5-chloro-1,3,4-thiadiazole-2-carboxamide (cf. EP 569810, Example 735), N-(2-chloro-6-methoxycarbonyl-phenylsulphonyl)-5-phenyl-1,3,4-thiadiazole-2-carboxamide (cf. EP 569810, Example 757), N-(2-chloro-6-methoxy-carbonyl-phenylsulphonyl)-5-methyl-isoxazole-3-carboxamide (cf.

EP 569810, Example 861), N-(2-chloro-6-methoxycarbonyl-phenylsulphonyl)-isoxazole-5-carboxamide (cf. EP 569810, Example 871), N-(2-chloro-6-methoxycarbonyl-phenylsulphonyl)-5-methyl-isoxazole-4-carboxamide (cf. EP 569810, Example 918) and N-(2-chloro-6-methoxycarbonyl-phenylsulphonyl)-3,5-dimethyl-isoxazole-4-carboxamide (cf. EP 569810, Example 925) have herbicidal properties (cf. also EP 341489, EP 422469, EP 425948, EP 431291, EP 507171, EP 534266, DE 4029753).
