摘要：A Pd-catalyzed hydrogenation of (Z)-trifluoromethyl alkenyl triflate providing either (Z) -or (E)-3,3,3-trifluoropropenyl derivatives with excellent divergent geometric control in good yield is described. Catalyzed by Pd(OAc)(2)/PPh3, the reduction of (Z)-trifluoromethyl alkenyl triflates with HSiEt3 gave (E)-3,3,3-trifluoropropenyl derivatives, and while using HCOOH/Et3N as the reducing agent, the (Z)-isomers were obtained through an elimination/hydrogenation tandem pathway. Both transformations showed excellent geometrical selectivity.
