PhI(OAc)2/I2-mediated [3+2] reaction of [60]fullerene with amides for the preparation of fullerooxazoles
An efficient synthesis of fullerooxazoles was developed via PhI(OAc)2/I2-mediated [3+2] reaction of C60 with amides under photo-irradiation. The reaction was tolerant to various aryl and alkyl amides. The reaction mechanism was investigated in detail and a radical pathway was proposed for the formation of fullerooxazoles. Further transformation of compound 2l allowed the easy conjunction of fullerooxazole

CuI-Catalyzed Oxidative [3 + 2] Reaction of Fullerene with Amidines or Amides Using Air as the Oxidant: Preparation of Fulleroimidazole or Fullerooxazole Derivatives
CuI-catalyzed oxidative reaction of amidines with C60 using air as the oxidant has been exploited for the easy preparation of fulleroimidazole derivatives. Furthermore, this kind of CuI-catalyzed [3 + 2] reaction has also been successfully applied in the synthesis of fullerooxazole derivatives starting from amides for the first time. The substrate scope is broad, and the process is particularly cheap

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
