| abstract |
The invention concerns compounds of formula (I), or salts thereof0, in which G is a group of the formula G?1, G2 or G3; R1¿ is H or alkyl; R2 is COOH, CSOH or a carboxylic- or thiocarboxylic-group derivative with 1 to 20 C-atoms or an acyl group of the CO-Ro type with 1 to 12 C-atoms or an imino, hydrazone or oxime derivative of the CO-Ro group, and R?o, R3a, R4a, R3b, R4b¿, W, X, Y and Z are as defined in claim 1. Such compounds are suitable for use as selective herbicides and plant-growth regulators in agricultural crop plants. They can be prepared by prior art methods via intermediates, some of which are novel, from the group comprising the benzenesulphonamides (II), benzenesulphonyliocyanates (IV), benzenesulphochlorides (VI) and heterocyclically substituted carbamates (III), amines (V) or [thio]isocyanates (XIX). |
