Oxidative Carbon-Carbon Bond Cleavage by Vanadium Catalyst
The aerobic oxidative CC bond cleavage of vicinal diols catalyzed by vanadium aminotriphenolates is described. Our results show that CC bond cleavag e can be performed in different solvents,under an air or oxygen atmosphere, with a large variety of glycols (cyclic or linear, with aromati c or aliphaticsubstituents) affording the corresponding carbonyl derivatives with high chemoselectivity.Reactions can be performed with as little as 10 ppm of catalyst reaching TON up to 81,000 and TOFs of up to4150 h1. A reaction mechanism, rationalized by de nsity functional theory calculations, is also proposed.
