Compounds of the formula (I) and salts thereof
in which R1 to R6, W, X, Y and Z are defined as in claim 1, have herbicidal or plant growth-regulatory properties.
They can be prepared by processes analogous to known processes (cf. claim 5), in some cases via novel intermediate products (cf. formula II):
