Decacarbonyldimanganese (Mn2(CO)10) is utilized as a phosgene equivalent for the one-pot preparation of unsymmetricalketones. By a successive treatment of Mn2(CO)10 with two kinds of alkyllithiums, unsymmetricalketones are obtained in high selectivity. Unsymmetrical α-diketones are generated when the above reaction is carried out in the presence of trimethyl phosphite and is quenched with N-bromosuccinimide
