    • Experimental Procedure: To an anhyd CH2Cl2 solution of the corresponding fullerene derivative 2 (1 equiv) in CH 2Cl2, tetramethylammonium nitrate (2 equiv) was added under Ar. The solution was cooled to the desired temperature and triflic anhydride (2 equiv) was added. NO2OTf was formed in situ and the solution was kept at this temperature until the complete disappearance of the starting material (the reaction progression was followed by TLC, The reaction was then quenched by adding a Na2CO3 solution (pH 8, The organic layer was separated, dried and evaporated. The remaining solid was purified by column chromatography affording the desired compounds 1a-d. Compound 1a: reaction temperature: -5°C for 4 h.
