协同反应的产物随反应条件的变化有着严格的选择定则。其机理可以用分子轨道图形理论或电子组态图去说明,但数学处理较复杂,本文用反应轨道相关图的方法对协同反应进行一些探讨,较为简便。当反应物变成产物时,反应物中心分子轨道发生转动变成产物的分子轨道,但反应物两个端碳P_Z轨道未发生反应,它与相邻碳原子的P_Z轨道相互平行,作用能为β。当反应时,端碳P_Z轨道旋转ψ角,则端碳的P_Z轨道各自和相互邻接的碳原子的P_Z轨道相交成一个ψ角,作
Synergistic reaction products with the reaction conditions have a strict selection rules. The mechanism can be described by the molecular orbital graph theory or the electronic configuration graph, but the mathematical processing is more complex. In this paper, the reaction orbital correlation graph method is used to discuss the synergistic reaction, which is simple and convenient. When the reactant becomes a product, the molecular orbital of the center of the reactant turns into the molecular orbit of the product, but the carbon orbit of the reactant does not react with the carbon orbit of P_Z. The P_Z orbital of the adjacent carbon atoms is parallel to each other and the action energy is β. When the reaction, the terminal carbon P_Z orbital rotation ψ angle, then the terminal carbon P_Z orbitals and carbon atoms adjacent to each other P_Z orbit intersects an ψ angle for
