Og. Khelevina et Aa. Voinov, Kinetic stability of the dysprosium(III) complex with tetraazaporphine in water-acetic acid and methanol-acetic acid mixtures, RUSS J C CH, 25(6), 1999, pp. 445-449
Water-soluble dysprosium tetraazaporphine complex with the acetylacetonate
ion as an extra ligand was synthesized for the first time. Its kinetic stab
ility in acetic acid solutions was studied. The complex was shown to underg
o solvoprotolytic dissociation to form free tetraazaporphine. The kinetic p
arameters for dissociation reaction are determined and the mechanism of rea
ction is discussed.
