CuCl₂-Mediated Reaction of [60]Fullerene with Amines in the Presence or Absence of Dimethyl Acetylenedicarboxylate: Preparation of Fulleropyrroline or Aziridinofullerene Derivatives

Abstract

The CuCl2-mediated three-component reaction of C60 with amines and dimethyl acetylenedicarboxylate afforded the fulleropyrrolines in moderate yields. Furthermore, the CuCl2-mediated oxidative [2 + 1] reaction of C60 with aromatic amines bearing a strong electron-withdrawing group provided the aziridinofullerenes and the selective cis-1-bisaziridinofullerenes.
