Homo- and hetero-dinuclear, diamagnetic and paramagnetic complexes of general formula [MeC(CH2PPh2)3]Rh(µ-H)3M(L)}n+[M = Rh, Co, Ni, L = MeC(CH2PPh2)3; M = Fe, L = MeC(CH2PEt2)3] have been synthesized and characterized; the electrochemical behaviour of the compounds shows that they reversibly undergo multisequential one-electron redox changes.

Disclosed is a process for the reductive carbonylation of a low molecular weight alcohol to produce the homologous aldehyde and/or alcohol. The process includes conducting the reaction to produce the aldehyde in the presence of a single component catalyst complex composed of cobalt, an onium cation and iodide in a ratio of 1:2:4 without additional promoters. A ruthenium co-catalyst is used in the production of the homologous alcohol. The reductive carbonylation reaction does not require an additional iodide promoter and produces a crude reductive carbonylation product substantially free of methyl iodide.
