Title: Oxidation catalyst system and method of oxidation with the same

Abstract: The oxidation catalyst system of the invention is composed of (A) a ruthenium compound and (B) a dioxybenzene or its oxidant. The ruthenium compound (A) includes dichlorotris(triphenylphosphine)ruthenium (II) and other ruthenium complexes and Ru/C. The dioxybenzene or its oxidant (B) includes hydroquinone. The oxidation of an alcohol by molecular oxygen in the presence of the oxidation catalyst system can give the corresponding carbonyl compound in high yield. A primary alcohol is more selectively oxidized than a secondary alcohol.
