Abstract

CuI-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.
