Process for the preparation of alkenylbenzenecarboxylic acid derivatives and alkenylnaphthalenecarboxylic acid derivatives

摘要

Compounds of the formula I (I) in which p, m, Z, R, R' and Y are as defined in claim 1, can be obtained in a simple and economical manner by a novel process which comprises reacting a halide of the formula (II) with the corresponding acrylic acid derivative, in the presence of a base and of certain palladium catalysts, such as palladium acetate. The compounds (I), and functional derivatives prepared therefrom, are useful for the preparation of photocrosslinkable polymers, which can in particular be employed as (so-called) photoresists.
