协同反应中许多问题的阐明,是在分子轨道对称守恒原理提出以后才系统化的.这个原理的基本论点就是当反应物和产物的轨道的对称性一致时,反应就易于进行;如果它们的对称性不一致,则反应难以进行,也就是在协同反应中分子轨道的对称性是守恒的.对轨道对称性守恒这一原理,已有几种分析方法.在提出这些理论的同时,有人从另一角度对这类反应的特点提出了其它解释.芳香过渡态理论就是其中之一.
The elucidation of many problems in the synergistic reaction is systematized after the conservation of the orbital symmetry conservation principle.The basic argument of this principle is that the reactions are easy to carry out if the symmetry of the reactants and the product orbit is consistent and if their symmetry Inconsistency, the reaction is difficult to carry out, that is, the symmetry of the molecular orbital in a synergistic reaction is conserved.There have been several analytical methods for the conservation of orbital symmetry.In addition to presenting these theories, Other explanations are provided for the characteristics of this type of reaction, the aromatic transition state theory is one of them.
