✦ Synopsis

Reaction of the cationic binuclear gold(I) complex [(Ph 3 PAu) 2 Cl]BF 4 with w-alkynylfurans furnished phenols as the major product and anellated furans as the side-products. The analogous trimesitylphosphane complex [(Mes 3 PAu) 2 Cl]BF 4 selectively afforded only the phenols. The latter catalyst then enabled the first intermolecular gold-catalyzed phenol synthesis.
