Abstract

Anionic fullerenes are nucleophilic reagents that can be easily generated by either chemically or electrochemically reductive methods. Electrochemical reduction is more convenient than chemical reduction since it is easy to generate the desired anions by controlling the potential and the charge transferred to the fullerene cages. Anionic C60 and C70 have been extensively used as nucleophilic reagents for fullerene functionalizations. The results clearly show the potential importance of fullerene anions as reagents to prepare functionalized fullerenes which are difficult to prepare in other ways. It is worth noting that different fullerene anionic states can lead to different products even under the same reaction conditions as a result of their different nucleophilicities. The chemistry of anionic fullerenes is an important complement to that of neutral species. The reactivity of anionic empty fullerenes is reasonably well developed, while the corresponding endohedral metallofullerene anions remain relatively less explored. The electrosynthetic method has not been widely applied to EMFs, and the reactivities of anionic EMF species have not been extensively studied. This prompted us to study the reactivity of EMF anions.
