ABSTRACT:
Compounds of the formula I ##STR1## in which A is C.sub.2-12 -alkenyl, C.sub.4-8 -cycloalkenyl or a grouping--C(R).dbd.C(R')--Y and Y, R, R', R.sub.1, R.sub.2, R.sub.3 and R.sub.3 ' are as defined in patent claim 1, can be prepared in high yields in a simple and economical manner by reacting corresponding bromobenzenes or iodobenzenes with a compound HA in the presence of an alkali metal salt or alkaline earth metal salt of an aliphatic monocarboxylic acid having 1-12 C atoms or benzoic acid, of a cyclic or N,N-disubstituted amide as the solvent, particularly N,N-dimethylformamide, and of a palladium compound which can, if desired, contain arsenic or phosphorus, as the catalyst.
