N-fluorobenzenesulfonimide based functionalization of C60.

The reaction of N-fluorobenzenesulfonimide (NFSI) with C60 and exploration of the product as a precursor for various 1,2- and 1,4-bisfullerene adducts are reported. NFSI is also found to act as an oxidant in the reaction of C60 with cyclic amines such as pyrrolidine yielding tetraaminoaziridino adducts.
