Abstract
Compounds of the formula I ##STR1## in which Z, Z.sub.1, R, m and p are as defined in patent claim 1, can be obtained in a simple and economical manner by a novel process wherein a halide of the formula II ##STR2## is reacted with a substituted or unsubstituted vinylbenzene or vinylnaphthalene derivative in the presence of a base and of certain palladium catalysts, such as palladium acetate. The compounds (I) or functional derivatives preparable therefrom are useful, for example, for the preparation of known dyes or fluorescent brighteners, or can be used directly as fluorescent brighteners or as scintillators.
