A Fast Route Toward the Preparative Isolation of Fullerene Isomers C78(1) and C78(2)

A new rapid approach toward the preparative isolation of individual C78‐fullerene isomers is suggested. The three most abundant representatives of this cage can be obtained in isomerically pure form in three consecutive stages. Chemical modification with ICl provides means for separation of isomers 1 and 2 through their halogenated derivatives, the thermal instability of which enables the soft regeneration of the parent fullerenes.
