Chemistry of Heterocyclic Compounds Aims and scope

Abstract

The nitration of 6-phenyl-2-pyridone with 70% nitric acid, nitronium tetrafluoroborate, and acetyl nitrate has been studied for the first time. It was shown that, depending on the reaction temperature, the nitro group enters the 3 or 5 position of the heterocyclic ring. 3- Nitro-6-(p-nitrophenyl)-2-pyridone is formed by the action of fuming nitric acid on 6-phenyl-2-pyridone. The structures of the nitropyridones obtained were proved by PMR spectroscopy.
