AB  - <jats:title>Abstract</jats:title><jats:p>Addition of CO to a tetrametallic magnesium hydride cluster results in both carboncarbon bond formation and deoxygenation to generate an acetaldehyde enolate [C<jats:sub>2</jats:sub>OH<jats:sub>3</jats:sub>]<jats:sup>−</jats:sup> which remains coordinated to the cluster. To the best of our knowledge, this is the first example of formation of an isolable complex containing an [C<jats:sub>2</jats:sub>OH<jats:sub>3</jats:sub>]<jats:sup>−</jats:sup> fragment from reaction of CO with a metal hydride, and the first example of CO homologation and deoxygenation at a main group metal. DFT studies suggest that key steps in the mechanism involve nucleophilic attack of an oxymethylene on a formyl ligand to generate an unstable [C<jats:sub>2</jats:sub>O<jats:sub>2</jats:sub>H<jats:sub>3</jats:sub>]<jats:sup>3−</jats:sup> fragment, which undergoes subsequent deoxygenation.</jats:p>
