Popis:	The electrochemical behavior of C{sub 60}O at a gold electrode in o-dichlorobenzene, dichloromethane, and a mixture of toluene and acetonitrile was studied in the potential range from 0.4 to -1.5 V. Three one-electron transfer steps were observed for C{sub 60}O within this potential window. The first and the third electron transfers are attributed to the reduction of the fullerene cage. The product of the first electron transfer is found to undergo a solvent- and rate-dependent decomposition to C{sub 60}. The irreversible transfer of the second electron, attributed to the presence of the epoxide oxygen, leads to a substantial change in fullerene structure and initiates polymer formation for which the kinetics of growth are found to be strongly solvent dependent. 21 refs., 9 figs.
