Copper‐Catalyzed Trifluoromethylation of Allylsilanes

Abstract

CF3 on C: Trifluoromethylation of allylsilane derivatives was accomplished through the use of CuI and Togni's reagent (1) under mild conditions. The reaction of allylsilanes without a substituent in the 2-position gave vinylsilane derivatives, while 2-substituted allylsilanes afforded desilylated products. The utility of the products was demonstrated through their further transformation.
