A visible-light-promoted method for the selective oxidation and cleavage of alkene C=C bonds to afford various aromatic ketones is reported by using Na2-Eosin Y as photocatalyst and oxygen as oxidant. This catalytic system presents excellent reaction performance, and only 1 mol% catalyst is required to achieve the conversion under mild conditions. Additionally, this protocol shows a broad substrate scope and good functional group tolerance. Moreover, the synthetic application value of this method was verified by a gram-scale experiment, and ketoprofen methyl ester and fenofibrate with medicinal value were successfully prepared with high yield. Mechanistic studies investigated the effects of superoxide radical anion on the reaction and a possible reaction mechanism was proposed accordingly.

Key words: visible-light, Na2-Eosin Y, alkene, oxidative cleavage, aromatic ketones
