Реферат: Compounds of formula (I), where R1, R2, n, W, R3 and A are as defined in claim 1, are suitable for use as herbicides and plant growth regulators. They can be produced by a process similar to known processes. To produce them, new com-pounds of formula (II) are reacted with a carbamate of formula R*-O-CO-NR3A, where R3 stands for phenyl or alkyl. The compounds of formula (II) can be obtained from the corresponding sulphochlorides.
