Fullerene-mixed peroxides C60(O)(OOtBu)4 and C60(OOtBu)6 are effective precursors for cage-opened fullerene derivatives. Lewis acids induce the heterolysis of peroxo O-O bond in C60(O)(OOtBu)4. Subsequent Hock-type rearrangement affords both [5,6]- and [6,6]-fullerene hemiketals - oxahomofullerene. Photolysis of C60(OOtBu)6 results in the homolysis of O-O and C-O bonds, affording fullerene diketone as the major product. Spectroscopic data and single-crystal analysis confirmed the cage-opening reactions.
