Photocatalyzed Hydroaminodifluoroalkylation of Alkenes

Abstract

AbstractThe synthesis of undescribed β‐aminodifluoroethylsulfinates and their uses in the hydroaminodifluoroalkylation of alkenes is reported. This reaction is performed in the presence of a photocatalyst (4CzIPN, Ru complexes) and enables the direct incorporation of a β‐difluoroamine moiety into vinylic aryls, unactivated alkenes, and electron‐rich, or ‐deficient alkenes. The mechanism was studied, and the formation of a gem‐difluoromethyl radical was observed after the selective oxidation of the sulfinate function.
