| 摘 要： | 利用热力学循环方法，通过ｐＫ和有关电化学数据的测定，首次得到了ＮＡＤ（Ｐ）Ｈ的辅酶模型物（ＢＮＡＨ）按不机理还原质子化Ｎ－芳基芴亚胺的各基元步骤的自由能变化，结合得到的同位素标纪结果，从热力学趋动力的角度区分了氢负离子的转移机理。

| Abstract: | Free energy changes of each primary steps in one-step hydride transfer and multistep transfer mechanisms in the reductions of protonated N-arylfluorenimines by an NAD (P) H model, BANH, were derived from approprlate thermodynamic cycles by combining PK. and relevant electrochemical data, The mechanism of the reduction was proposed as onestep hydride transfer from thermodynamic points of view and the isotope-labelling experiments. |
