一、前言有机化合物分子中,电子诱导效应与化合物的性质密切相关,深刻研究其间的关系有着重要的理论意义和实际意义。蒋明谦提出了基团诱导效应指数的概念及其计算方法。在此工作的基础上,我们增加了空间结构对诱导率的贡献,完善了带电原子共价半径与电负性的修正公式;对环状化合物提出等长最短诱导途径相容,非等长路取最短链传递的原则,给出一个寻找所有最短通路的简便方法;将[1]中基团诱导指数的概念扩充为化合物键极性诱导效应指数的概
I. INTRODUCTION Among the organic compounds, the electron-induced effect is closely related to the properties of the compounds. It is of great theoretical and practical significance to deeply study the relationships among them. Jiang Mingqian proposed the concept of group induced effect index and its calculation method. On the basis of this work, we increase the contribution of space structure to the induction rate and improve the correction formula of the covalent radius and the electronegativity of charged atoms. We propose a compatible equation for the cyclic compound with the shortest induction route of equal length and non-equal length Taking the principle of shortest chain transfer, a simple method to find all the shortest paths is given. The concept of group induction index in [1] is extended to the index of the compound key polarity induction effect
