摘要：
In the course of liquid-phase catalytic oxidation, the coordination spheres and three-dimensional structures of the Cu-II complexes with various polyamine anion exchangers are changed. The main regularities of these changes were studied by ESR and IR spectroscopy. It was demonstrated that these transformations occur stepwise, which is associated with successive oxidation of the coordinated amino groups of the polymer-metal complexes in the reactions with the participation of molecular oxygen and hydrogen peroxide. The possible mechanisms of transformation of the metal complexes is discussed.
