Patent number: 6525211
Abstract: The invention relates to novel sulphonylamino(thio)carbonyl compounds of the formula (I),
in which
A 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,
R1 represents hydrogen or formyl or represents in each case optionally substituted alkyl, alkenyl, alkinyl, alkylcarbonyl, alkoxycarbonyl, alkylsulphonyl, cycloalkyl, cycloalkylcarbonyl or cycloalkylsulphonyl,
R2 represents cyano or halogen or represents in each case optionally substituted alky, alkenyl, alkinyl, alkoxy, alkenyloxy or alkinyloxy, and
R3 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),
the previously known compounds 4,5-dimethoxy-2-(2,5-dimethoxy-phenylsulphonylaminocarbonyl)-2,4-dihydro-3H-1,2,4-triazol-3-one, 4,5-die
