Description

Extracomplexes of Ru(2) octaphenyltetraazoporphine with pyridine and pyrazine have been studied by the methods of cyclic and differential pulsed voltammetry and spectroelectrochemistry. In dichloromethane quasireversible processes of metal central atom oxidation with formation of ruthenium(3) complexes and reduction of macrocyclic ligand are observed. It is shown that strong π-acceptor properties of tetraazaporphyrin macrocyclic ligand stabilize the lowest oxidation states of metal-complexing agent

Abstract (Russian)

Методами циклической и дифференциальной вольтампероетрии и спектроэлектрохимии исследвоаны экстракомплексы октафенилтетраазапорфинаторутения(2) с пиридином и пиразином. В дихлорметане наблюдаются квазиобратимые процессы окисления центрального атома металла с образованием комплексов рутения(3) и восстановления макроциклического лиганда. Показано, что сильные π-акцепторные свойства тетраазапорфиринового макроциклического лиганда стабилизируют низшие степени окисления металла-комплексообразователя
