摘要：

AbstractThe metal exchange reaction of Mg(II)-octa-(4-fluorophenyl)tetraazaporphyrin with Co(II), Cu(II), and Mn(II) chlorides in dimethylformamide has been studied by the spectrophotometric method. The kinetic parameters were calculated and the stoichiometric mechanism of the metal exchange reaction was established. The influence of the solvate salt nature and the tetrapyrrole macrocycle chemical modification on the kinetic parameters of the studied reaction was revealed. Using the metal exchange reaction of Mg(II)-octa-(4-fluorophenyl)tetraazaporphyrin with CoCl2 in dimethylformamide, Co(II)-octa-(4-fluorophenyl)tetraazaporphyrin was synthesized. Co(III)-octa-(4-fluorophenyl)tetraazaporphyrin was obtained by treating Co(II)-porphyrazine with a dimethylformamide-hydrochloric acid mixture. The processes of cobalt complexes oxidation and reduction in solvents of various natures were studied.
