具生物功能的二氧四胺大环配合物的研究──Ⅲ．十三元二氧四胺大环铜（Ⅱ）配合物的K_2S_2O_8氧化反应

STUDIES ON MACROCYCLIC DIOXOTETRAAMINE COMPLEXES WITH BIOLOGICAL FUNCTIONS──Ⅲ. K_2S_2O_8 Oxidation of Copper(Ⅱ) with 13-Membered Macrocyclic Ligands

用紫外可见光谱跟踪Ｋ２Ｓ２Ｏ８对［Ｃｕ（Ｈ_２ｄｔ）］及［Ｃｕ（Ｈ_２ｎｐｄｔ）］的氧化过程，研究［ＣｕⅢＨ_２Ｌ］＋配合物的生成、分解反应动力学，获得了拟一级反应的速率常数和表现活化能。配合物［Ｃｕ（Ｈ_２ｄｔ）］的氧化速度比带有取代基［Ｃｕ（Ｈ_２ｎｐｄｔ）］的更快。

By K2S2O8 oxidation of monocyclam(dt,npdt) complexes, we studied the kineties of the formation and degeneration of Cu Ⅲ complexes using UV-visible Spectra and obtained rate constants and observed activation energies of the pseudo-first-order reactions.[Cu(H_2dt)] oxidized faster than that of [Cu(H_2npdt)] .
