Kinetic Features of the Formation of Zinc Complex with Hexa(m-Trifluoromethylphenyl)benzoporphyrazine in a Nitrogen-Containing Base–Benzene System
摘要:
The effect n-butylamine, tert-butylamine, piperidine, and morpholine additives have on the kinetics of complex formation between zinc acetate and hexa(m-trifluoromethylphenyl)benzoporphyrazine in benzene is studied. A possible scheme for their complexation is proposed. It is established that the rate and activation parameters of the process are affected by the proton-acceptor capacity of the base and its spatial structure.

The regularities of intermolecular proton transfer from β-substituted porphyrazines to dimethylsulfoxide, cyclic and acyclic nitrogen-containing bases in inert solvents are considered. We found that the process rates are unusually low. We showed that the acidic properties of a porphyrazine macrocycle, the proton-acceptor ability of a base, and the dielectric constant of the environment influence the
