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

One-Pot Method for Regioselective Bromination and Sequential Carbon-Carbon Bond-Forming Reactions of Allylic Alcohol Derivatives
An efficient one-potmethod for the regioselective bromination of allylicalcoholderivatives (two-step reaction sequence) followed by Sonogashira, Negishi, or Suzuki–Miyaura coupling reactions in the same reaction vessel (three-step reaction sequence) has been developed. The key reaction in these one-pot systems is the regioselective DBU-promoted trans HBr elimination of vicinal dibromides bearing
