对称禁阴反应的催化,是当前催化化学的重要解题,引起了国内外学者的重视。本文运用分子轨道对称守恒原理对如何选用合适的催化剂,使一个禁阴的反应,变为允许的反应进行了研究,从理论上分析了过渡金属及其络合物在催化对称禁阴反应过程中所起的作用,并对催化剂具备的条件以及催化剂作用的实质提出了看法。 The catalysis of symmetrical forbidden shade reaction is an important solution to the current catalysis chemistry, which has aroused the attention of domestic and foreign scholars. In this paper, the theory of molecular orbital symmetry conservation is used to study how to choose a suitable catalyst to make a forbidden anion reaction into a permissive reaction. The theoretical analysis of the transition metal and its complex during the catalytic symmetric forbidden anion reaction Played a role, and the catalyst has the conditions and the nature of the role of the catalyst put forward their views.
