A mild green and efficient approach for hydrogen peroxide oxidative converting oximes to the corresponding carbonyl compounds with a water-soluble manganese porphyrin as catalyst in water/acetone mixture has been developed. The water-soluble manganese porphyrin showed an excellent activity for the oxidative deoximation reactions of various oximes under ambient conditions in the absence of any additive. The oxidative deoximation was through the formation of high valent oxo-manganese species, which was confirmed by in situ UV-vis spectroscopy.
