Abstract

The invention relates to novel sulphonylamino(thio)carbonyl compounds of the formula (I), ##STR1## in which PA1 A represents a single bond, oxygen, sulphur or the group N--R, in which R represents hydrogen, alkyl, alkenyl, alkinyl or cycloalkyl, PA1 Q represents oxygen or sulphur, PA1 R.sup.1 represents hydrogen or formyl or represents in each case optionally substituted alkyl, alkenyl, alkinyl, alkylcarbonyl, alkoxycarbonyl, alkylsulphonyl, cycloalkyl, cycloalkylcarbonyl or cycloalkylsulphonyl, PA1 R.sup.2 represents cyano or halogen or represents in each case optionally substituted alkyl, alkenyl, alkinyl, alkoxy, alkenyloxy or alkinyloxy, and PA1 R.sup.3 represents 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), PA1 the previously known compounds 4,5-dimethoxy-2-(2,5-dimethoxy-phenylsulphonylaminocarbonyl)-2,4-dihydro-3 H-1,2,4-triazol-3-one, 4,5-diethoxy-2-(2,5-dimethoxy-phenylsulphonylaminocarbonyl)-2,4-dihydro-3H -1,2,4-triazol-3-one PA1 and N-(2,5-dimethoxy-phenylsulphonyl)-1,5-dimethyl-1H-pyrazole-…
