Abstract

Chemical functionalizations of an endohedral metallofullerene, La2@Ih-C80, and an empty fullerene, C60, are demonstrated using organosulfur compounds. A novel donor–acceptor system of La2@Ih–C80-exTTF (3) synthesized using the Prato reaction shows photo-induced intramolecular charge separation. On the other hand, the photoreaction of C60 with N-p-toluenesulfonyl sulfilimine affords N-tosyl-1,2-aziridinofullerene (5). The first reversible interconversion of 1,2-aziridinofullerene and 1,6-azafulleroid was found for mono-substituted fullerenes by thermal rearrangement of 5 to 6. S,S-Diphenylsulfilimines (7) with an electron-donating group on the N atom reacts with C60 to afford corresponding aziridinofullerenes (810) regioselectively.
