Chemical functionalizations of an endohedral metallofullerene, La 2@Ih-C80, and an empty fullerene, C 60, are demonstrated using organosulfur compounds. A novel donor-acceptor system of La2@Ih/s
[2+1] Cycloaddition of nitrene onto C60 revisited: Interconversion between an aziridinofullerene and an azafulleroid

(Figure Presented) An open and closed case: The reversible interconversion of a [1,2]aziridinofullerene and a [1,6]azafulleroid represents the first such example for a monosubstituted fullerene. While the [1,2]aziridinofullerene rearranges thermally to th

The hypervalent iodine reagent mediated reaction of C60 with various readily available amines for the easy preparation of iminofullerenes has been developed. The reaction between C60 and sulfonamides can be effectively controlled to

A PCy3-catalyzed ring-expansion reaction of aziridine-fused fullerenes (aziridinofullerenes) through the insertion of CO2 and aryl isocyanates is disclosed. The reaction allows for CO2 fixation by aziridinofullerenes, producing oxazolidinone-fused fullerenes (oxazolidinofullerenes) in high yields, whereas treatment with aryl isocyanates led to a new fullerene family - imidazolidinone-fused fullerenes (imidazolidinofullerenes) - in good to high yields. Furthermore, a mechanistically related unprecedented fullerenyl phosphonium salt was successfully isolated. Using the isolated salt, mechanistic studies were also investigated. New balls please: A PCy3-catalyzed ring-expansion reaction of aziridine-fused fullerenes (aziridinofullerenes) by the insertion of CO2 and aryl isocyanates is disclosed (see scheme). This allows for CO2 fixation by aziridinofullerenes. The expansion with aryl isocyanates led to a new fullerene family, imidazolidinone-fused fullerenes, in high yields. A mechanistically related unprecedented fullerenyl phosphonium salt was also successfully isolated (Cy=cyclohexyl). Copyright
Aziridinofullerene: A Versatile platform for functionalized fullerenes

An aziridine moiety on the fullerene core can serve as an acid-triggered reacting template for the controlled synthesis of a range of functionalized fullerenes that are otherwise difficult to synthesize in an efficient and selective manner. A copper-catal
