Electrochemical oxidation and reduction of rhodium and iridium complexes with fullerenes C60 and C70

Abstract

The electrochemical behavior of rhodium and iridium complexes with fullerences C60 and C70 was studied by cyclic voltammetry in a THF—toluene mixture. The complexes were found to be capable of oxidation and reduction. It was demonstrated that thein situ generation of metallofullerene complexes in the electrochemical cell by the interaction of C60 and C70 with hydridocarbonylphosphine complexes of rhodium and iridium, HM(CO)(PPh3)3, is possible. The influence of structural factors and the action of CO2 on changes in the redox properties of fullerene complexes was considered.
