ABSTRACT:
The invention relates to novel sulphonylamino(thio) carbonyl compounds of the formula (I),in whichA represents a single bond, oxygen, sulphur or the group N—R, in which R represents hydrogen, alkyl, alkenyl, alkinyl or cycloalkyl,Q represents oxygen or sulphur,R1represents hydrogen or formyl or represents in each case optionally substituted alkyl, alkenyl, alkinyl, alkylcarbonyl, alkoxycarbonyl, alkylsulphonyl, cycloalkyl, cycloalkylcarbonyl or cycloalkylsulphonyl,R2represents cyano or halogen or represents in each case optionally substituted alkyl, alkenyl, alkinyl, alkoxy, alkenyloxy or alkinyloxy, andR3represents in each case optionally substituted heterocyclyl having 5 ring members of which at least one is oxygen, sulphur or nitrogen and from one to three further ring members can be nitrogen,and salts of compounds of the formula (I),the previously known compounds 4,5-dimethoxy-2-(2,5-dimethoxy-phenylsulphonylaminocarbonyl)-2,4-dihydro-3H-1,2,4-triazol-3-one, 4,5-diethoxy-2-(2,5-dimethoxy-phenylsulphonylaminocarbonyl)-2,4-dihydro-3H-1,2,4-triazol-3-oneand N-(2,5-dimethoxy-phenylsulphonyl)-1,5-dimethyl-1H-pyrazole-3-carboxamide being excluded by disclaimer;and also to processes and novel intermediates for the preparation of the novel substances and to their use as herbicides.
