Abstract

The invention relates to novel sulfonylamino(thio)carbonyl compounds of the formula (I), in whichn represents the numbers 0, 1 or 2,A represents a single bond, or oxygen or sulfur, or the grouping N—R, in which R represents hydrogen, alkyl, alkenyl, alkinyl or cycloalkyl,Q represents oxygen or sulfur,R1 represents hydrogen or formyl, or represents respectively optionally substituted alkyl, alkoxy, alkylamino, alkoxyamino, dialkylamino, N-alkoxy-N-alkyl-amino, alkylcarbonyl, alkoxycarbonyl, alkylsulfonyl, alkenyl, alkinyl, cycloalkyl, cycloalkylcarbonyl or cycloalkylsulfonyl,R2 represents cyano or halogen, or represents respectively optionally substituted alkyl, alkoxy, alkylthio, alkylsulfinyl, alkylsulfonyl, dialkylaminosulfonyl, alkenyl, alkinyl, alkenyloxy or alkinyloxy, andR3 represents respectively optionally substituted heterocyclyl having 5 ring members of which at least one is oxygen, sulfur or nitrogen and from one to three further ring members can be nitrogen,and salts of compounds of the formula (I), a plurality of processes and novel intermediates for preparing them and their use as herbicides.
