有机硅材料是一种功能独特,性能优异的化工新材料,广泛应用于工业、农业、医药等各大领域。其种类繁多,如硅油、硅橡胶、硅树脂、硅烷等,它们的主要成分均为有机硅化合物,且均非自然界中存在的天然物质,需人工合成。目前,烯烃硅氢化反应是制备有机硅化合物的重要方法之一。该方法简单而直接,且具有原子经济性,备受人们的亲睐。这类反应需要在催化剂的作用下才能发生,因而过渡金属催化剂的设计和机理的研究一直为实验和理论工作者所关注。本文综述了近年来过渡金属配合物催化剂及其催化烯烃硅氢化反应的机理。重点介绍了Pt、Rh、Ru、Zr等过渡金属配合物的不同催化作用机制,希望为以后的研究提供思路和启发。
Silicone material is a kind of chemical new material with unique function and excellent performance. It is widely used in various fields such as industry, agriculture and medicine. Its wide range, such as silicone oil, silicone rubber, silicones, silanes, etc., are the main components of organic silicon compounds, and are not naturally occurring in nature, need to be synthesized. At present, the hydrosilylation of alkenes is one of the important methods for preparing organosilicon compounds. The method is simple and direct, and has atomic economy, much people’s pro-gaze. Such reactions need to occur under the action of the catalyst, so the design and mechanism of transition metal catalysts have been of interest to both experimental and theoretical workers. In this paper, the mechanism of transition metal complex catalysts and their catalytic hydrogenation of alkenes were reviewed in recent years. The different catalysis mechanisms of Pt, Rh, Ru, Zr and other transition metal complexes are mainly introduced, hoping to provide ideas and inspiration for future research.
