摘要：

The electrochemical transformations and antiradical activity of trialkylantimony(V) o-amidophenolate derivatives, (AP)SbR3 (AP = 4,6-di-tert-butyl-N-(2,6-diisopropylphenyl)-o-amidophenolate); R = CH3 (I), C2H5 (II), and C6H11 (III), are studied. The electrochemical oxidation of compounds I-III proceeds successively to form mono- and dicationic forms of the complexes. The presence of the donor hydrocarbon groups at the antimony(V) atom shifts the oxidation potentials to the cathodic range and decreases the stability of the monocationic complexes formed in electrochemical oxidation. The second anodic process is irreversible and accompanied by o-iminoquinone decoordination. The antiradical activity of compounds I-III is studied in the reaction with the diphenylpicrylhydrazyl radical and oleic acid autooxidation. The values obtained for indices EC50 and IC50 indicate the antiradical activity of the studied compounds. Complexes I-III were found to be the efficient inhibitors of oleic acid oxidation and act as efficient destructors of hydroperoxides.
