摘要：

Reaction of tetra-n-butylammonium nitrate and triflic anhydride, CF3SO2OSO2CF3 (Tf2O), in dichloromethane (CH2Cl2) solvent at O degrees C, produces anhydrous nitronium nitrate, NO2OSO2CF3 (NO2OTf). Subsequent introduction of various heterocycles and their N-acetylated analogs yield N-nitrated products in 20-76% yield with an overall one-pot procedure.
