Solvent-Free Synthesis of N-Arylfulleropyrrolidine Derivatives Without Using Phase-Transfer Catalyst Under Microwave Irradiation

Abstract

Several N-arylfulleropyrrolidine derivatives were synthesized via the direct solvent-free reactions of N-unsubstituted fulleropyrrolidines and nitrochlorobenzenes under microwave irradiation in the absence of phase-transfer catalysts. Their structures were confirmed by ultraviolet–visble, Fourier transform–infrared, ¹H NMR, and mass spectrometry.
