Abstract

Sulfur-substituted phenylsulfonylureas; processes for their preparation and their use as herbicides and plant growth regulators Compounds of the formula (I) and salts thereof ##STR1## in which R*, R.sup.1, R.sup.2, R.sup.3, X, Y, Z, W, n and m are defined as in claim 1, and specifically R* is a formyl equivalent of the formula CHO, --CH.dbd.NR or CH(X.sup.1 R')(X.sup.2 R"), are suitable as herbicides and plant growth regulators. They are prepared analogously to known methods, in some cases using novel intermediate products of the formula (XVII) ##STR2## in which U*.dbd.NH.sub.2, Cl or (substituted) amino.
