aerobic oxidative C−C bond cleavage of vicinal diols catalyzed by vanadium amino triphenolates is described. Our results show that C−C bond cleavage can be performed in different solvents, under an air or oxygen atmosphere, with a large variety of glycols (cyclic or linear, with aromatic or aliphatic substituents) affording the corresponding carbonyl derivatives with high chemoselectivity.

描述了钒氨基三酚盐催化邻位二醇的好氧氧化CC键裂解。我们的结果表明,在空气或氧气气氛下,可以使用多种乙二醇(环状或直链,具有芳族或脂肪族取代基)在不同溶剂中进行C-C键裂解,从而提供具有高化学选择性的相应羰基衍生物。可以在低至10 ppm的催化剂下达到TON达到81,000和TOF达到4150 h -1的情况下进行反应。还提出了通过密度泛函理论计算合理化的反应机理。
