| Abstract: | CO2 functionalization to afford beneficial products is one of the current scientific greatest challenges. Amongst all the possible transformations, the synthesis of formic acid from CO2 is of high interest due to the enormous industrial production of this chemical. Particularly interesting is the obtention of formic acid via transfer hydrogenation (TH) of CO2, allowing milder reaction conditions and eliminating the need to employ a hazardous gas as H2. Iridium catalysts promoted TH reactions have been widely studied; however, examples of TH to CO2 are very scarce. In our search for the development of new and more efficient catalysts, we have studied the ability of [IrCp*(QO)X] complexes (QO = 8‐oxyquinolinate) to promote TH to bicarbonate salts and CO2 to obtain formate salts. The study shows a crucial ligand effect, obtaining the best results when [IrCp*(5,7‐Me,Me‐QO)Cl] was employed. Under optimized conditions, TON values up to 135 and 60 were obtained for TH to bicarbonate salts, and CO2, respectively. Remarkably, [IrCp*(5,7‐Me,Me‐QO)Cl] is able to trap and transform atmospheric CO2 into formate salts. [ABSTRACT FROM AUTHOR] |
