In conclusion, we have found and developed K2CO3 catalyzed oxidation of αhydroxy ketone including Benzoin and DHMF to the corresponding carbonyl compounds using air under mild reaction conditions. The solvent, additives, catalysts and catalyst loading, reaction time, and reaction temperature are evaluated. With the water trapping additive AC, oxidation of benzoin could be converted to benzil in 94.9% yield with a catalytic amount of 10% K2CO3 after 5 hours in DMSO under an open-air system. Moreover, for the first time, a catalytic amount of 10% K2CO3 showed excellent reactivity in the oxidization of DHMF, and the desired oxidized product benzil was obtained in 98% yield using solvent H2O under an open-air system without any other additives.
