Copper Catalyzed Fluoroalkyl‐Selenization of Olefins

Abstract An efficient copper catalyzed fluoroalkyl‐selenization reaction of olefins has been developed, providing 1,2‐difluoroarylselenides in moderate to excellent yields. The readily available ethyl bromodifluoroacetate and diphenyl diselenide (Ph 2 Se 2 ) have been employed as efficient radical precursor and selenization reagents to react with olefins. The reaction features a broad substrate scope, including substituted alkenes with various functional groups.
