摘要
讨论了芳香族双分子亲核取代反应中离去基电子效应的作用 .从反应实例出发 ,通过对卤族离去基在作用物及中间体中电子效应的分析 ,结合反应历程 ,运用有机基本理论 ,定性论述了在该类反应中离去基的电负性、电子效应 。
In this paper,the action of electronic effect of leaving groups on S NAr reactions was discussed.On the basis of reaction examples,through analyzing electronic effect of halogen leaving groups in reacting substance and intermediate complex,combining reaction mechanisms,adopting basic organic theories,the corresponding relations between electro negativity,electronic effect,especially induction effect of leaving groups and reacting rate were explained qualitatively.
