characterized. These iron compounds are efficient and selective catalysts for the anti-Markovnikov alkene hydrosilylation of primary, secondary, and tertiary silanes. More importantly, the system exhibits unprecedented functional group tolerance with reactive groups such as ketones, esters, and amides. Furthermore, the iron-catalyzed alkene hydrosilylation was successfully applied to the synthesis of a valuable
已制备并表征了一系列具有供电子性次膦酸盐-亚氨基吡啶 (PNN) 配体的新型钳铁配合物。这些铁化合物是伯、仲和叔硅烷的抗马尔科夫尼科夫烯烃氢化硅烷化的有效和选择性催化剂。更重要的是,该系统对酮、酯和酰胺等反应性基团表现出前所未有的官能团耐受性。此外,铁催化的烯烃氢化硅烷化成功地应用于合成一种有价值的杀虫剂硅氟醚。已经通过光谱学和计算方法研究了铁配合物的电子性质和结构。总的来说,铁催化剂可以为目前用于烯烃氢化硅烷化的贵金属系统提供一种低成本和环境友好的替代品。
