Vinyl-halides-and-phenols, 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.. A general procedure for vinyl aryl ether bond formation by direct coupling of vinyl halides and phenols under mild ullmann-type reaction conditions has been developed. using copper chloride as the..., a general procedure for vinyl aryl ether bond formation by direct coupling of vinyl halides and phenols under mild ullmann-type reaction conditions has been developed. using copper chloride as the catalyst and cesium carbonate as the base, vinyl bromides or iodides were reacted with phenols in refluxing toluene to produce vinyl aryl ethers in good to excellent yields..
