Abstract
A cobalt(i) complex is shown to be capable of both electrocatalytic reduction and hydrogenation of CO2 to formate. Several proposed intermediates are characterized and thus form the basis for a proposed mechanism that allows for the dual reactivity: reduction of CO2via H2 addition, and H+/e- equivalents. The work makes use of a novel tris(phosphino) ligand. When a pendent amine is attached to the ligand, no change in catalytic reactivity is observed.
摘要
一种钴（I）配合物被证明能够将二氧化碳电催化还原并氢化生成甲酸盐。对几种提出的中间体进行了表征，从而为一种允许双重反应性的机制提供了基础：通过添加氢气还原二氧化碳，以及氢离子/电子当量。这项工作使用了一种新型的三（膦基）配体。当在配体上连接一个侧链胺时，未观察到催化反应性的变化。
