An efficient method for the synthesis of fluoropyridines by the fluorodenitration reaction is reported. The reaction was mediated by tetrabutylammonium fluoride under mild conditions without undue regard to the presence of water. The fluorodenitration was general for 2- or 4-nitro-substituted pyridines, while 3-nitropyridines required attendant electron-withdrawing groups for the reaction to proceed efficiently. Nitropyridines also underwent hydroxy- and methoxydenitration under mild conditions in the presence of the corresponding tetrabutylammonium species.
