Substituted sulphonylamino (thio) carbony/compounds

The invention relates to novel substituted sulphonylamino(thio)carbonyl compounds of the formula (I)in whichA represents oxygen, sulphur, NH, N-alkyl, N-aryl, -CH=N-, or -N=CH-or -CH=CH-,Q represents oxygen or sulphur,R1 represents respectively optionally substituted alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkylalkyl, aryl, arylalkyl, heterocyclyl or heterocyclylalkyl,R2 represents cyano, nitro, halogen or represents respectively optionally substituted alkyl, alkoxy, alkoxycarbonyl, alkylthio, alkylsulphinyl, alkylsulphonyl, alkenyl, alkinyl, alkenyloxy or alkinyloxy, andR3 represents respectively optionally substituted heterocyclyl having 5 ring members of which at least one represents oxygen, sulphur or nitrogen and a further one to three may represent nitrogen,(except for certain individual prior art compounds), furthermore to salts of novel compounds of the formula (I), to various processes and novel intermediates for preparing the novel compounds and to their use as herbicides.
