苯环上亲电取代反应的定位规则及应用

The Positioning Rules and Application of Electrophilic Substitution Reaction on Benzene Ring

苯作为重要的工业合成原料,由于苯环上有多个取代位置,因此对苯环进行二元取代时会产生不同的取代产物,所以通过苯环上进行取代反应定位规则的研究可以对其取代反应进行产物预测,同时苯环上的取代反应在有机合成的反应中有着重要的作用,但其合成过程中产生的副反应比较多,因而对其取代反应的定位规则的研究以及在有机合成的应用研究就显得极其重要。

Benzenes is an important raw material in the industrial synthesis.Benzene ring has multiple substitution position, as the result, disubstituted reaction of benzene ring produces different products.The research on the positioning rules of substitution reaction on the benzene ring can project the products producing by the reaction , and it plays an important role in organic synthesis reaction as the frequent side reaction in the synthesis.
