Metal‐Free Visible‐Light Radical Iodoperfluoroalkylation of Terminal Alkenes and Alkynes

Abstract

The organic‐dye‐catalyzed visible‐light‐induced iodoperfluoroalkylation of unactivated terminal alkenes and alkynes was explored. This process was found to be effective for the simultaneous introduction of iodide and various perfluoroalkyl groups (including difluoroacetate) to alkenes and alkynes possessing a variety of functional groups. A possible reaction mechanism is proposed. This reaction provides a new, metal‐free, green method for the synthesis of perfluoroalkylated compounds.
