title: Regioselective synthesis of [60]fullerene eta 5-indenide R3C60- and eta 5-cyclopentadienide R5C60- bearing different R groups.
abstract: Treatment of a 1,7-diorgano[60]fullerene with Grignard reagents or organocopper reagents affords a [60]fullerene indenide or a [60]fullerene cyclopentadienide regioselectively in good to excellent yields. These reactions gave an insight into the reaction mechanism of the organocopper penta-addition reaction of [60]fullerene, giving [60]fullerene cyclopentadienide in quantitative yield.
