carbonyl sulfonylamino (thio)

The invention concerns novel sulphonylamino(thio)carbonyl compounds of formula (I) in which: A stands for a single bond, oxygen, sulphur or the N-R group, R standing for hydrogen, alkyl, alkenyl, alkinyl or cycloalkyl; Q stands for oxygen or sulphur; R stands for hydrogen, formyl or for in each case optionally substituted alkyl, alkenyl, alkinyl, alkylcarbonyl, alkoxycarbonyl, alkylsulphonyl, cycloalkyl, cycloalkylcarbonyl or cycloalkylsulphonyl; R stands for cyano, halogen or for in each case optionally substituted alkyl, alkenyl, alkinyl, alkoxy, alkenyloxy or alkinyloxy; and R stands for in each case optionally substituted heterocyclyl with 5 ring members, of which at least one can be oxygen, sulphur or nitrogen, and between one and three further ring members can be nitrogen; as well as salts of compounds of formula (I), the previously known compounds 4,5-dimethoxy-2-(2,5-dimethoxy-phenyl-sulphonylaminocarbonyl)-2,4-dihy dro-3H-1,2,4-triazol-3-one, 4,5-diethoxy-2-(2,5-dimethoxy-phenylsulphonylaminocarbonyl)-2,4-dihydr o-3H-1,2,4-triazol-3-one and N-(2,5-dimethoxy-phenylsulphonyl)-1,5-dimethyl-1H-pyrazole-3-carboxamide being excluded by disclaimers. The invention further concerns processes and novel intermediate products for preparing the novel substances and their use as herbicides.
