The reaction of C-60 to acylnitrenes 2, generated by photolysis of aroylazides 1 in dichloromethane, creates the stable fulleroaziridine derivatives 3a, 3b, 3c, and 3d. The rearrangement of the fulleroaziridines 3 by boiling in tetrachloroethane leads to the formation of the corresponding fullerooxazoles 4a, 4b, 4c, and 4d. The formation of a fullerooxazole 4b was also observed by irradiation of C-60 and 1b in benzene.
