Abstract

The metal exchange reactions of Cd(II)-5-(4-nitrophenyl)-10,15,20-triphenylporphyrin and Cd(II)-5,10,15-tri-(4-nitrophenyl)-20-phenylporphyrin with cobalt and zinc chlorides in dimethylformamide were studied by the spectrophotometric method. The kinetic parameters of metal exchange were calculated and a possible stoichiometric mechanism of the process is established. The influence of the nature of the solvate salt and the chemical modification of the tetrapyrrole macrocycle on the kinetic parameters of the metal exchange reaction was revealed.
