Kinetic Features of the Formation of Zinc Complex with Hexa(m-Trifluoromethylphenyl)benzoporphyrazine in a Nitrogen-Containing Base–Benzene System

Abstract

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.
