One of the golden dreams of current catalysis research is the development of catalysts that can use CO2 as a feedstock,possibly in large-volume transformations.Unfortunately, only a minor fraction of the available CO is transformed catalytically in industrial processes, owing to its chemical inertness.The reactivity of CO with M–X bonds (X = C, O, N) is one of the most puzzling organometallic reactions,because of the kinetic and thermodynamic stability of CO Any new organometallic complex or chemical mechanism that is able to perform or explain the capture of CO is extremely interesting.Very recently,anewIr I complex,[Ir(cod)(IiPr)(OH)] ;cod = 1,5-cyclooctadiene; IiPr = 1,3-diisopropylimidazol-2-ylidene),was shown to fix CO both in solution and in the solid state to form a dimeric structure of 16-electron fourcoordinate and 18-electron five-coordinate Ir centers (see Scheme 1).
