The photoinduced electrochemical oxidation of benzyl alcohol to benzaldehyde in acidic acetonitrile proceeded with practically 100% product selectivity and ca. 100% current efficiency under visible-light irradiation in the presence of riboflavin-2′,3′,4′,5′-tetraacetate (RF) as a mediator. A double mediatory system involving duroquinone as well as RF resulted in remarkable acceleration of the benzaldehyde formation with maintenance of both the high product selectivity and high current efficiency.
