Photolysis of butyrophenone, valerophenone, γ-methylvalerophenone, and acetophenone in methanol in the presence of triphenylphosphine gave triphenylphosphine oxide and 1-phenyl-1-methoxyalkanes in addition to the expected Norrish type II products.Kinetic studies of these photoreactions by steady-state measurements show that triplet-state ketones are quenched by Ph3P but that the corresponding biradicals do not interact with Ph3P.
