摘　　要：总结了存在电荷转移复合物反应的反应历程的研究结果 ,在 Diels-Alder反应和氢负离子转移反应中观测到负的表观活化焓 ,表明电荷转移复合物是真正的反应中间体。Charge transfer (CT) complexes formed between electron donors and acceptors have been studied extensively.It has been considered impossible to distinguish kinetically whether CT compleses are real intermediates in the reactions so far.This review summarizes the results of CT complexes studies with focusing on the mechanistic aspects.Negative observed activation enthalpies obtained in hydride transfer reactions and in Diels Alder reactions indicate that CT complexes act as true intermediates in these reactions.
