Abstract

A new method for the synthesis of trifluoromethyl-allenes from easily accessible α-trifluoromethyl-propargyl benzyl ether derivatives following a gold-catalyzed intramolecular hydride transfer has been developed. Various di- and trisubstituted trifluoromethyl-allenes were obtained in good to excellent yields.
