Abstract

Eosin Y catalyzes an efficient photochemical aerobic oxidation of various benzyl alcohols to the corresponding aldehydes or ketones in excellent yields under mild reaction conditions using O₂ as oxidant. The catalyst system offers good functional-group tolerance and exquisite chemoselectivity.
