This protocol is characterized by excellent yields, mild conditions, low catalyst loading, and broad scope. In addition, the atom transfer protocol can be used to quickly and efficiently introduce vinyl trifluoromethyl groups to olefins and access 1,1-cyclopropane diesters. 2011-03-30 00:00:00 Ir vinyl trifluoromethyl groups halocarbonyl atom transfer protocol olefins access scope photocatalyst Intermolecular Atom Transfer Radical Addition cyclopropane haloalkane diester Olefins Mediated Oxidative Quenching catalyst loading yield Photoredox CatalystsAtom transfer
