对位取代四苯基卟啉铜(II)的生成动力学及其它金属离子的影响
摘要:
本文用Shimadzu UV-240紫外可见分光光度计对Cu(Ⅱ)与对位取代四苯基卟啉H_2(p-X)TPP(X=NO_2, (Cl,H,CH_3,OCH_3)在二甲亚砜溶剂中的生成动力学及镉(Ⅱ)离子对该反应的催化作用进行了系统研究, 提出了反应机理, 并观察了Hg(Ⅱ)、Pb(Ⅱ)等其它金属离子对此反应的影响。发现反应速率常数及平衡常数与Hammett取代常数σ值之间呈现良好的直线自由能关系。

Kinetics of the Formation of (Para-Substituted Tetraphenylporphinato)-Copper(II) and the Catalytic Effect of Other Matal Ions
Abstract:
The kinetics of formation reaction of Copper(Ⅱ) with para-substituted tetraphenylporphyrin H_2(p-X)TPP (X=NO_2,Cl,H, CH_3,OCH_3) in dimethyl sulfoxide solution and the catalytic effect of Cadmium(Ⅱ) ion have been studied on Shimadru UV-240 spectrophotometer. The mechanisms were proposed and the effect of Hg(Ⅱ), Pb(Ⅱ) on this reaction was investigated. od LFER (linear free energy relationahips) between reaction rate constant/equilibrium constant with the Hammett subtituent constant σ have been ob served in certain cases.
