Benzothiophenes are prepared by intramolecular Pd(0)-catalyzed Heck reaction of allyl o-iodophenyl sulfides.Pd(0)-Catalyzed intramolecular cyclization of o-iodophenyl propargyl sulfide in the presence of a hydride donor gives 3-methylene-2,3-dihydrobenzothiophene, which reacts with several enophiles in ene type reactions.However, allyl (and propargyl) aryl sulfides react with palladium(II) chloride to afford polymeric
