The kinetics of coordination of porphyrins of different structure with intracomplex copper salts of α-amino acids (glycine, α-alanine, valine) in DMSO has been studied. N-Methyl-5,10,15,20-tetraphenylporphine, with a planar structure disturbed by the introduction of the methyl group into the coordination center, and 2,3,7,8,12,13,17,18-octaphenyltetraazaporphyrin, with a more rigid aromatic system than in porphyrins, react with the α-amino acid complexes of copper(II) faster than 5,10,15,20-tetraphenylporphine. The salt structure has the most dramatic effect on N-methyl-5,10,15,20- tetraphenylporphine coordination. Steric factors are less important when an increase in the ability of the macrocycle to complex formation is ensured by the electron component of the macrocyclic effect.
