Palladiumcatalysedcoupling of vinyl bromides proceeds in good yield under mild conditions provided sufficient triarylphosphine and potassium carbonate are present to regenerate the active palladium(0) species; double bond isomerisation is not observed under these conditions.

Palladium acetate (5 mol %) effects catalytic inter-and intra-molecular coupling of vinyl bromides in good yield under mild conditions provided sufficient triarylphosphine and potassium carbonate are present to regenerate the active palladium(O) species. Wilkinson's catalyst is a poor catalyst for the same coupling reaction. Double bond isomerisation is not observed under these conditions. The palladium
