  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 catalyst complex composed of cobalt, an onium cation and iodide in a ratio of 1:2:4 with a phosphine ligand. 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.
