The electroreductions of Buckminsterfullerene (C{sub 60}) in aprotic solvents were examined as a function of solvent, supporting electrolyte, and temperature. Altogether, 11 different solvents and 17 different supporting electrolytes were utilized in measurements made between 223 and 348 K. The cations of the supporting electrolytes were Li{sup +} and Na{sup +} as well as quaternary ammonium and quaternary phosphonium cations. The anions of the supporting electrolytes were ClO{sub 4}{sup {minus}}, BF{sub 4}{sup {minus}}, PF{sub 6}{sup {minus}}, and Br{sup {minus}}. Cyclic voltammograms, rotating disk electrode voltammograms, and controlled potential coulometry revealed up to five reversible one-electron reductions. A qualitative approach is used to elucidate the effects of solvent, supporting electrolyte and temperature on the half-wave potentials, E{sub 1/2}, of the reductions of C{sub 60}. A qualitative approach is used to elucidate the effects of solvent, supporting electrolyte, and temperature on the half-wave potentials, E{sub 1/2}, of the reductions of C{sub 60}. 38 refs., 5 figs., 7 tabs.
