Kinetic stability of complexes of conjugated macroheterocycles with metals in a proton-donor medium

The rate of decomposition of conjugated macroheterocyclic ligands containing isoindole and 1,2,4-thiadiazole residues has been studied together with the rate of dissociation of their complexes with copper, cobalt, and zinc in a proton-donor medium at three temperatures. Rate constants and activation parameters have been determined for the decomposition of the macrocyclic ligands and the dissociation of their complexes.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 2, pp. 268–271, February, 1990.
