Cycloadditions to [60]fullerene using microwave irradiation: A convenient and expeditious procedure
摘要:
Several Diels-Alder and 1,3-dipolar cycloadditions to C-60 were performed, under microwave irradiation, in a modified domestic microwave oven and a focused microwave reactor. Reactions proceed within minutes to afford the respective cycloadducts in similar or increased yields related to the described methods by conventional heating. This methodology simplifies the procedure and overcomes the drawbacks resulting from the long reaction times required under classical heating conditions. (C) 1997, Elsevier Science Ltd.

Solvent-Free Synthesis of <i>N</i>-Arylfulleropyrrolidine Derivatives Without Using Phase-Transfer Catalyst Under Microwave Irradiation
Several N-arylfulleropyrrolidine derivatives were synthesized via the direct solvent-free reactions of N-unsubstituted fulleropyrrolidines and nitrochlorobenzenes undermicrowaveirradiation in the absence of phase-transfer catalysts. Their structures were confirmed by ultraviolet–visble, Fourier transform–infrared, 1H NMR, and mass spectrometry.
