Visible Light‐mediated Tandem Addition/Elimination Reaction of Iododifluoromethyl Ketones and Alkenes

Abstract A new and efficient synthesis of allyl difluorides has been developed via visible light‐mediated photoredox‐catalyzed tandem addition/elimination reaction of iododifluoromethyl ketones and alkenes. This method has demonstrated mild conditions and broad substrate scope tolerance, and has offered an alternative way for direct fluoroalkylation of alkenes.
