银配合物与联氨定向反应的研究II. 酸度与温度对定向反应影响

本文研究了酸度和温度对银配合物与联氨定向反应的影响, 在不同的pH和温度下, 微量Cu(II)离子的加入均能有效地提高N2H4的四电子定向反应率; N2H4的四电子反应率随体系pH和温度的提高吾有序增加, 无Cu(II)离子存在时, N2H4的四电子反应率与银配合物logβ2呈线性关系。Cu(II)离子存在时, N2H4单电子反应率的对数与1/logβ2呈线性关系。

Studies on the directional reaction of silver coordination compounds with hydrazine

The directional reaction of hydrazine with several Ag coordination compounds was studied at different acidities and temps. If a trace amount of Cu3+ is present in the reaction system, the 4-electron directional reaction of hydrazine is greatly increased under different pH or temperature conditions. The ratio of 4-electron directional reaction of hydrazine increases with the increasing of pH value or temperature The ratio of 4-electron reaction against log b2 of several Ag coordination compounds is linear in the absence of Cu2+. In the presence of Cu2+, the logarithm of the ratio of 1-electron reaction of hydrazine is proportional to 1/log b2.
