摘要:
Compounds of formula (I), where R.sup.1, R.sup.2, n, W, R.sup.3 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 compounds of formula (II) are reacted with a carbamate of formula R.sup.* --O--CO--NR.sup.3 A, where R.sup.3 stands for phenyl or alkyl. The compounds of formula (II) can be obtained from the corresponding sulphochlorides.
