Cu2+ reaction with I gave pH and ionic strength dependent kinetics. The equilibrium constant for association of I with ClO4- was determine spectroscopically to be 3.70 M-1 and the product had 1:1 stoichiometry. Temperature dependence of the kinetics yielded activation parameters and a mechanism involving porphyrin ring deformation is discussed.
