摘要：

The synthesis of nitroderivatives of 5,15-diphenyltetramethyltetraethylporfin was carried out. Reactions of complexation of nitroderivatives of 5,15- tetraethyltetramethyl-diphenylporphyrin with zinc acetate in pyridine and mixed solvent acetic acid-benzene (7:3) were studied. Nitro group in the 5,15- tetraethyltetramethyl-diphenylporphyrin are in meso-positions of the tetrapyrrole macrocycle and (or) the para-positions of the phenyl rings. The rate of formation of zinc complexes in pyridine at the introduction of nitro groups in the 5,15- diphenyltetramethyltetraethylporfin was established to increase in the growth of the deformation degree of the tetrapyrrole macrocycle and the weakening its NH-bonds. In the binary solvent acetic acid-benzene (7:3) the effect of deformation of the macrocycle leads to the decrease in the rate of reaction due to the specific solvation of the reaction site of porphyrin by molecules of acetic acid.
