The selective formation of aziridinofullerene and azafulleroid, which are isomers of the fullerene derivatives-introduced N1 unit, is achieved. The ionic aziridination is a very convenient and risk-free procedure compared with the conventional method with azides as nitrogen sources, and gives aziridinofullerenes from various readily available amides (carbamates, ureas, carboxamides, and phosphamides). For example, benzyl carbamate ...
