A palladium-catalyzed oxidative dehydrogenation enables an efficient synthesis of 1,4-enediones from saturated ketones in the presence of molecular oxygen as the sole oxidant. This atom- and step-economic process offers broad substrate scope, good functional group tolerance, and complete E-stereoselectivity.
