Isolation of the endohedral metallofullerenes is currently carried out via a multistage high-performance liquid chromatography (HPLC) method. However, this method is tedious andtime-consuming work, making it difficult to obtain macroscopic quantities of pure endohedralmetallofullerenes. We report herein a selective electrochemical reduction of the endohedralmetallofullerenes from extracts of carbon soot and a convenient separation method ofendohedral metallofullerenes and empty fullerenes. A chemical oxidation of the endohedralmetallofullerene anions is also discussed.
