The reductive ring opening reaction conditions for the simple fullerenyldihydropyrrole 1 have been optimized to include acetic acid in the reaction mixture to rapidly protonate the anionic intermediate. Under these conditions, the ring opened dihydrofullerene 2 was obtained in 68% yield. Under slightly modified conditions and at −78 °C, the reductive bis-ring opening of the tethered trans -4 isomer 3 provided the novel racemic bis-dihydrofullerenyl derivative 7.
