Generation of CF₃‐Containing Epoxides and Aziridines by Visible‐Light‐Driven Trifluoromethylation of Allylic Alcohols and Amines

Radical reactions! Efficient methods for the generation of CF3-containing epoxides and aziridines have been developed (see scheme). A variety of allylic alcohols and allylic amines were transformed into the corresponding epoxides and aziridines by using [Ru(bpy)3]Cl2 (bpy = 2,2'-bipyridine), CF3 I, and 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) (or N,N,N',N'-tetramethylethylenediamine, TMEDA) under visible-light irradiation.
