A range of aryl bromides undergo a Heck vinylation reaction with a protected allyl alcohol in the presence of[PdCl(C3H5)]2/cis,cis,cis-1,2,3,4-tetrakis(diphenylphosphan-ylmethyl)cyclopentane as a catalyst. The reactivity of these allyl alcohol derivatives using a variety of protecting groups has been studied. The best results in terms of substrate/catalyst ratio were obtained with a THP protecting
