Abstract: | The electroreduction of a binuclear complex of copper(II) with a macrocyclic Schiff base of the Robson type on the basis of 4-tert-butyl-2,6-diformylphenol and 1,3-diaminopropane on the dropping-mercury, gold, amalgamated-gold, and glassy-carbon electrodes is studied in an aqueous environment. The data of experiments on preparative electrolysis and the results of measurements by a method of cyclic voltammetry and classic polarography suggest that the complex under study undergoes reduction in an aqueous environment with the transfer of four electrons with formation of copper(0) and a free Schiff base, which in conditions under investigation experiences hydrolytic decomposition. |
