range of 2-arylbenzo[b]furans are synthesized through domino intermolecular C(aryl)–C(alkynyl) bond formation followed by intramolecular C(alkynyl)–O bond forming cyclization via copper(II)-catalyzed coupling of o-iodophenols and aryl terminal acetylenes. This method requires neither expensive palladium catalyst nor oxophilic phosphine ligands, can tolerate different functional groups. The methodology
