摘要: 应用量子化学密度泛函理论在UB3LYP/6-31G(d)水平上, 结合MP4和AM1方法研究了苯的溴代反应过程. 计算结果表明, 这是包括一个过渡态和两个中间态的多步反应, 反应过程中Br+所带的正电荷经正离子中间体[C6H6Br]+转移给H, 是电子转移过程.

关键词: 密度泛函, B3LYP, 溴代反应, 电子转移

Abstract: We used the density functional theory at UB3LYP/6-31G(d) level, to study the process of bromine substituting for hydrogen on the benze ne ring. From the results of the calculations, it is a multistep reaction including a transition state and two intermediate states. A positive charge of Br+ transfers to H by means of intermediate [C6H6Br]+. In fact, it is a process of electron transfer.

Key words: density functional theory, B3LYP, bromine reaction, el ectron transfer
