The multisite bound acetylide in M2(CO)6(μ-η2-C≡CPh)PPh 2) (M = Ru, Fe) reacts with CO in the presence of primary and secondary amines NHRR′ to generate via carbonylation and amination the μ-keto compounds M2(CO)6[μ-O=CCHC(Ph)NRR′](PPh2) (2). X-ray analyses of 2 (M = Ru, R = R′ = Et) and 2 (M = Fe, R = Ph, R′ = H) revealed the presence of oxygen and carbon bonded acyl groups with regiospecific addition of the amine to the original β-alkynyl carbon atom. These μ-O,C complexes may be closely related to species implicated in the reduction of CO by H2 to oxygenates in the presence of binuclear catalysts. The possible use of this reductive carbonylation strategy for the elaboration of other multisite bound carbocationic ligands is suggested.
