The ferric perchlorate-mediated reactions of C60 with various nitriles in o-dichlorobenzene under nitrogen atmosphere afforded the rare fullerooxazoles, which would be difficult to prepare by other methods. A possible reaction mechanism for the formation of the fullerooxazoles was proposed.

efficient copper-mediated [3 + 2] heteroannulation reaction of [60]fullerene with N-hydroxybenzimidoyl cyanides has been developed for the synthesis of fullerooxazoles. A possible reaction mechanism involving unique C–CN and N–OH bond cleavages and subsequent C–OH bond formation for N-hydroxybenzimidoyl cyanides is proposed to explain the generation of fullerooxazoles. In addition, the formed fullerooxazoles
internal-oxidant relay cascade reaction has been developed by functionalization of O-substituted benzohydroxamic acids or N-chloro-arylamides with [60]fullerene. Depending on the nature of the N-substituted groups, fullerenooxazoles or rare hydroxyfullerenyl amides could be obtained in a straightforward and flexible manner. Such a new transformation provides a unique strategy for the synthesis of fullerenooxazoles
