Stoichiometric carbon dioxide reduction to highly reduced C1 molecules, such as formic acid (2e ), formaldehyde (4e ), methanol (6e ) or even most-reduced methane (8e ), has been successfully achieved by using organosilanes, organoboranes, and frustrated Lewis Pairs (FLPs) in the presence of suitable catalyst. The development of renewable organohydride compounds could be the best alternative in this regard as they have shown promise for the transfer of hydride directly to CO . Reduction of CO by two electrons and two protons to afford formic acid by using renewable organohydride molecules has recently been investigated by various groups. However, catalytic CO reduction to ≥2e -reduced products by using renewable organohydride-based molecules has rarely been explored. This Minireview summarizes important findings in this regard, encompassing both stoichiometric and catalytic CO reduction.
通过使用有机硅烷、有机硼烷和受阻路易斯对（FLP）在合适的催化剂存在下，成功地将化学计量的二氧化碳还原为高度还原的 C1 分子，如甲酸（2e）、甲醛（4e）、甲醇（6e）甚至最还原的甲烷（8e）。在这方面，开发可再生有机氢化物化合物可能是最好的选择，因为它们在直接将氢化物转移到 CO 方面显示出了前景。最近，不同的研究小组研究了使用可再生有机氢化物分子将 CO 还原为两电子和两质子，以甲酸的形式获得甲酸。然而，使用可再生有机氢化物基分子催化 CO 还原为≥2e-还原产物的研究很少。这篇综述总结了这方面的重要发现，包括化学计量学和催化 CO 还原。
