Abstract

The acid dissociation of tetraphenylporphyrazine (H2PA(Ph)4) and octa(4-bromophenyl)porphyrazine (H2PA(4-BrPh)8) and their reactions with Cd2+ ions were studied in DMSO at 298 K. The equilibrium formation constants of the complexes and the acid dissociation constants of porphyrins were calculated; their relationship with the stability constants of the complexes was analyzed. The acidity sequence for porphyrazine derivatives was established.
