Hg(Ⅱ)配合物与N_2H_4定向反应的研究

Studies on the Directional Reactions of Mercury (Ⅱ) Coordination Compouds with Hydrazine

本文研究了Hg(Ⅱ)配合物与N_2H_4的定向反应,得出该反应为定量四电子反应,该反应随反应体系pH值增大,反应速度加快。Cu(Ⅱ)是该反应有效的催化剂.文中讨论了该反应的反应机理,N_2H_2是该反应主要中间体,通过在反应液中加入不饱和酸已成功地截获N_2H_2.

The directional reactions of N2H4 with several iron(Ⅲ) coordination compounds have been studied. We found that while increasing pH value the reaction rate increases and the ratio of four-electron reaction of N2H4 increases and one-electron reaction becomes subordinate. Copper(Ⅱ) is an effective catalyst for these reactions. The reaction mechanism has been discussed.
