摘要
Salts of the formula (I) IMAGE in which n is 0, 1, 2 or 3, R is halogen, alkyl or alkoxy, mainly in each case independently of other substituents R in the event that n is greater than 1, R1 is a substituted or unsubstituted hydrocarbon radical or a substituted or unsubstituted heterocyclic radical, R2 is an acyl radical, R3 is hydrogen or C1-C5-alkyl, M(+) is a metal or ammonium ion, X and Y independently of one another are halogen, C1-C6-alkyl, C1-C6-alkoxy or C1-C6-alkylthio, each of the three last-mentioned radicals being unsubstituted or substituted by one or more radicals selected from the group consisting of halogen, C1-C4-alkoxy and C1-C4-alkylthio, or are C3-C6-cycloalkyl, C2-C6-alkenyl, C2-C6-alkynyl, C3-C6-alkenyloxy, C2-C6-alkynyloxy, mono- or di(C1-C4-alkyl)amino, and Z is CH or N, are suitable as herbicides and plant growth regulators, The compounds (I) can be prepared by processes of claims 5 to 7, for example by hydrogenating 2-alkoxycarbonyl-5-nitrophenylsulfonylureas in the presence of anhydrides.
