The electron-transfer reactions of several binary metal carbonyls at a Pt electrode in aprotic solvents have been investigated. In tetrahydrofuran, cathodic reduction the M(CO)n leads to anions [M2(CO)2n– 2]2–(M = Cr, Mo, W, and Fe) [M(CO)n]–(M V), while binuclear M2(CO)10(M Mn Re) gives [M(CO)5]–. Of anodic reactions, particular interest are oxidations Cr(CO)6 which, acetonitrile, produce cations [Cr(CO)6]+ [M(CO)5(NCMe)]+ respectively. mechanisms these studied.
