Controlled Synthesis of a Range of 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-catalyzed aziridination of C60 for the practical synthesis of aziridinofullerene and acid-catalyzed reactions of aziridinofullerene with mono- and bifunctional nucleophiles as well as alkynes are described. The rapid generation of structural diversity in a single chemical operation using the common platform is notable.
