Abstract : We are establishing the coordinated ligand reactions depicted for reducing CO2 to formaldehyde and methanol; our objective in future studies includes optimizing and combining these ligand reactions into a reaction cycle or a catalytic system. Our approach exploits bimetallic complexation of carbon dioxide and uses a third metal system as the reductant (e.g., catalytic hydrosilation). These bimetallic CO2 adducts feature synergistic CO2 binding in which an electron-rich metal system LxM contributes metallocarboxylate binding and an oxophilic LyM system sequesters one or both metallocarboxylate oxygens (2a and 2b, respectively). In addition ot stabilizing the CO2 adduct, the resulting electronic 'push-pull' also activates the CO2 ligand as a hydride acceptor.
