亲电取代反应亲电取代反应顾名思义，是亲电试剂取代其它官能团的化学反应。被取代的基团通常是氢，但其他基团被取代的情形也是存在的。亲电取代是芳香族化合物的特性之一。芳香烃的亲电取代（Electrophilic aromatic substitution，常缩写为 SEAr）是一种向芳香环系，如苯环上引入官能团的重要方法。若如此分类，另一种主要的亲电取代反应是脂肪族的亲电取代。

Electrophilic substitution 亲电取代反应Electrophilic substitution reactions are chemical reactions in which an electrophile displaces a functional group in a compound, which is typically, but not always, a hydrogen atom. Electrophilic aromatic substitution reactions are characteristic of aromatic compounds, and are important ways of introducing functional groups onto benzene rings. The other main type of electrophilic substitution reaction is an electrophilic aliphatic substitution reaction. |
