  • Method for producing compound with carbonyl group by using ruthenium carbonyl complex having tridentate ligand as dehydrogenation oxidation catalyst
    Patent number: 9000212
    Abstract: Provided by the present invention is a method for efficient oxidation of alcohols by using, as a catalyst for dehydrogenation oxidation, a ruthenium complex which can be easily produced and easily handled and is obtainable at a relatively low cost. The invention relates to a method of producing a compound having a carbonyl group by dehydrogenation oxidation of alcohols by using as a catalyst the ruthenium carbonyl complex represented by the following general formula (1) RuXY(CO)(L) (1) (in the general formula (1), X and Y may be the same or different from each other and represent an anionic ligand, and L represents a tridentate aminodiphosphine ligand).
