摘要
芳香族化合物在酸的作用下可发生可逆的氢交换。该过程是质子对芳香环作亲电进攻,生成过渡态的芳烃离子,后者再失去氢离子完成了氢的化学交换,因而本质是亲电取代反应。
The exchange between hydrogen atoms attached to carbon atoms of heterocycliccompounds and deuterium of deutero-trifluoroacetic acid was confirmed by ~1H NMR.Therate of exchange depends upon the extent to which molecules are charged.The kinetics ofexchanges were investigated.
