Cul-catalyzed coupling reaction of vinyl halides and phenols occurs at 60-90 °C with N,N-dimethylglycine hydrochloride as the additive, giving vinyl aryl ethers in good yields. The cross-coupling products formed from o-iodophenols and vinyl iodides are converted into substituted benzofurans via an intramolecular Heck reaction.
