Study on the Kinetics of the Insetting Reaction of Cu(II) and T_(γNPN)P_(Y)P

The kinetics of the insetting reaction of Cu(Ⅱ) and γ-tetra-(4-cyanoethylpyridyl)-porphyrin were studied in KCl,KBr,KI,KNO_(3) solutions at pH value 1.5～3.0(35℃).The rate constant equation was given by linear regression analysis.Coinciding with stability of the complexes,the rate of insetting reaction decreased in the following order:KCl KBr KIKNO_(3).The results indicated that the anion ions were involved in the coordination.
