easily reducible aromaticcarbonyl compounds. Herein, we describe a mild, metal-free ketone–olefin coupling reaction using an excited-state acridine radical super reductant as a photoredox catalyst. We demonstrate both intramolecular and intermolecular ketone–olefin couplings of aliphatic and aromaticketones and aldehydes. Mechanistic evidence is also presented supporting an “olefin first” ketone–olefin
