Electrophilic substitution reaction

Japanese: 求電子置換反応 - きゅうでんしちかんはんのう(英語表記)electrophilic substitution reaction
Electrophilic substitution reaction
Substitution reaction by electrophilic reagents. Electrophilic reagents generally behave as cations or similarly. For example, in the case of nitration of benzene, NO 2 + acts as an acceptor of the π electrons of benzene and forms a π complex. It then forms a σ bond with one carbon atom to form a σ complex, and then passes through a new π complex to release H + , completing the substitution.

Japanese:
求電子試薬による置換反応。求電子試薬は一般に陽イオンあるいはそれに類似の行動をとるもので,たとえばベンゼンのニトロ化の場合,NO2+ はベンゼンのπ電子の受容体として働き,π錯体をつくる。次いで1つの炭素原子とσ結合してσ錯体となり,さらに新たなπ錯体を経て H+ が放出されて置換が完結すると考えられる。
