Abstract
The acid-base interaction of octa(p-bromophenyl)tetraazaporphine with nitrogen-containing organic bases in benzene-DMSO system is studied. The structures of the proton-transfer complexes formed in the reaction are suggested. The reaction rate, activation parameters, and mechanism of intermolecular transfer of protons of the NH groups of octa(p-bromophenyl)tetraazaporphine to a base were shown to be determined by the nature of the proton-acceptor molecules. The dielectric permeability of a binary solvent was found to significantly affect the kinetic parameters of the process.
