Abstract

A procedure was suggested for direct measurement of the equilibrium constant of complex formation of porphyrins MX2 + H2P ⇄ MP + 2HX, based on providing conditions under which the direct reaction is suppressed and the reverse reaction is facilitated. The procedure is applicable to complexation of Cd2 + with tetrachloro- and tetrabromotetraazaporphyrins in DMSO in the presence of HClO4.
