Abstract
The kinetics of complexation between octa(p-bromophenyl)tetraazaporphine an d magnesium acetylacetonate in a benzene solution with additions of pyridin e, 2-methylpyridine, n-butylamine, and diethylamine was studied. The basici ty of the medium was shown to influence the kinetic parameters of the proce ss. The scheme is suggested for the formation of the Mg complex with octa(p -bromophenyl) tetraazaporphine in the organic base-benzene system. The role of acid-base interactions in the coordination of magnesium(II) with bromo- substituted octaphenyltetraazaporphine is discussed.
