ABSTRACT:
Acylated aminophenylureas, preparation and use as herbicides and plant growth regulators
The compounds of the formula I or their salts ##STR1## in which G is a radical G1, G2 or G3 ##STR2## R.sup.1 is H or alkyl, R.sup.2 is COOH, CSOH or a derivative of the carboxyl or thiocarboxyl group, of 1 to 20 carbon atoms, or acyl of the type CO-R.degree. of 1-12 carbon atoms, or an imino, hydrazone or oxime derivative of the group CO-R.degree., and R.degree. , R.sup.3a, R.sup.4a, R.sup.3b, R.sup.4b, W, X, Y and Z are as defined in claim 1, are suitable as selective herbicides and plant growth regulators in crops.
The preparation is carried out in analogy to known processes (see claim 5) by way of intermediates, some of which are new, from the group consisting of benzene-sulfonamides (II), benzenesulfonyl isocyanates (IV) and benzesulfonyl chlorides (VI) and heterocyclically substituted carbamates (III), amines (V) and/or (thio)-isocyanates (XIX).
