(Equation presented) Fullerene cyclopentadienide (PhCH2)2Ph3C60- and indenide (PhCH2)2PhC60-, each bearing two different organic groups, were efficiently synthesized through regioselective reactions of 1,4-(PhCH2)2C60 with an organocopper reagent (PhMgBr/CuBr-SMe2) or a Grignard reagent (PhMgBr) followed by deprotonation with KOtBu.
