Abstract

N-[(Pyrimidin-2-yl)aminocarbonyl]benzenesulfonamide of the general formula I ##STR1## where R.sup.1 is methyl or ethyl; PA1 R.sup.2 is hydrogen or methyl; PA1 R.sup.3 is unsubstituted or substituted alkyl; PA1 a group ER.sup.6, in which E is O or S, R.sup.6 being unsubstituted or fluorine-substituted alkyl, with the exception of difluoromethoxy, and, if E is O and at the same time R.sup.5 is trifluoromethyl, R.sup.6 may furthermore be methylsulfonyl, ethylsulfonyl, trifluoromethylsulfonyl, allylsulfonyl or propargylsulfonyl; PA1 NO.sub.2 or OH; PA1 dialkylaminosulfonyl if R.sup.5 is fluorine; PA1 C.sub.1 - or C.sub.2 -alkylsulfonyl which may carry 1 to 3 halogen atoms; PA1 R.sup.4 is hydrogen, methyl, ethyl, methoxy, ethoxy, fluorine, chlorine, methylthio, ethylthio or C.sub.1 or C.sub.2 -haloalkoxy; and PA1 R.sup.5 is fluorine or trifluoromethyl, and their environmentally compatible salts, processes for their preparation and their use.
