denticity of the ancillary ligands. In a few cases, the addition of Lewis acids to zinc hydride catalysts markedly influences carbon dioxide reduction. These factors have been investigated by exploring elementary reactions of carbon dioxide hydrosilylation and hydroboration by using cationic zinc hydrides bearing tetradentate tris[2‐(dimethylamino)ethyl]amine and tridentate N,N,N′,N′′,N′′‐pentamethyldiethylenetriamine
近年来,锌已成为减少二氧化碳的一种选择元素。锌化合物已被展示为二氧化碳氢化硅烷化和硼氢化反应的催化剂。二氧化碳减少的程度取决于多种因素,包括锌中心的亲电性和辅助配体的密度。在少数情况下,向氢化锌催化剂中添加路易斯酸会显着影响二氧化碳的还原。通过使用带有四齿三[2-(二甲基氨基)乙基]胺和三齿N,N,N ',N '',N的阳离子氢化锌探索二氧化碳加氢甲硅烷基化和硼氢化的基本反应,研究了这些因素。在三苯基硼烷和三(五氟苯基)硼烷存在下的''-五甲基二亚乙基三胺。
