Abstract
The 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.
期刊介绍：
Russian Journal of General Chemistry is a journal that covers many problems that are of general interest to the whole community of chemists. The journal is the successor to Russia’s first chemical journal, Zhurnal Russkogo Khimicheskogo Obshchestva (Journal of the Russian Chemical Society ) founded in 1869 to cover all aspects of chemistry. Now the journal is focused on the interdisciplinary areas of chemistry (organometallics, organometalloids, organoinorganic complexes, mechanochemistry, nanochemistry, etc.), new achievements and long-term results in the field. The journal publishes reviews, current scientific papers, letters to the editor, and discussion papers.
