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