Hydrofluoroalkylation of alkenes with organozinc reagents under photocatalytic conditions is described. The fluorinated alkyl radicals were generated from organozincs by the single electron oxidation of the carbon-zinc bond. The radical addition step is followed either by hydrogen atom transfer for unactivated olefins or by a reduction/protonation sequence for strongly accepting arylidenemalononitriles.
