The palladium-catalysedarylation of ten 1,1- and 1,2-disubstituted activated alkenes with benzoyl chloride was studied. In most cases, more than one product was formed. The stereochemical course of the arylation appears to be controlled by the polarity of the double bond, the tendency to cis (suprafacial) alkene insertion and subsequent re-elimination, steric hindrance in the alkylpalladium(II) species

Compounds of the formula I ##STR1## 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 ##STR2## 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.
