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. Good LFER (linear free energy relationahips) between reaction rate constant/equilibrium constant with the Hammett subtituent constant σ have been ob served in certain cases.
