A quick fix : The recently reported process of “oxygen‐atom metathesis”, which is akin to olefin metathesis, may be involved in the activation of carbon dioxide. Nucleophilic attack by the d 8 metal center of an in situ generated Fischer carbene complex on carbon dioxide affords an unstable metallacycle. Elimination of an organic component, tert ‐butyl formate, results in the concurrent formation of an iridium–carbonyl complex.
