Unstable products from the ozonation of C-60 in solvents

The ozonation of a solution of C-60 in toluene results in the formation of several unstable compounds C60X and C60Y[1-5] which decay completely at roo m temperature within about 1 h. The products are oxides C60O[6,6], C60O2[I] , C60O2[II], and possibly an isomer of C60O3 The transformations are not du e to oxidation by atmospheric oxygen but are spontaneous. The ozonation of a solution of C60O[6,6] in toluene results in the formation of two unstable compounds C(60)Z[1-2] which also decay completely to C60O2[I] and C60O2[II ] It is suggested that all. unstable "parents" are ozonides.
