A variety of organic hydride donors (OHDs) have been tested as reagents for the transfer of hydride to iron formato complexes in the activation and reduction of carbon dioxide. Theoretical calculations show that the selection of OHD and solvent is crucial when planning systems involving OHD cooperativity. Strong consideration is given to the likelihood that metal centers may deactivate formate to hydride
已经测试了多种有机氢化物供体(OHD)作为在二氧化碳的活化和还原过程中将氢化物转移至甲酰铁络合物的试剂。理论计算表明,在计划涉及OHD合作性的系统时,选择OHD和溶剂至关重要。强烈考虑了金属中心可能使甲酸酯失活而发生氢化物侵蚀的可能性,因为通常而言,与有机甲酸酯或甲酸相比,与金属中心络合时,甲酸酯基团具有更多的共振稳定能。实验证明1,2-二氢吡啶不是有效的二氧化碳还原剂。
