A General Procedure for the Fluorodenitration of Aromatic Substrates.-Treatment of several nitroarenes, e.g. (I) and (III), with potassium fluoride in the presence of phthaloyl difluoride or tetrafluorophthaloyl difluoride as a nitrite ion trap results in fluorodenitration, forming the corresponding fluoroaromatic compounds ( II) and (IV) respectively. Analogously, the substituted fluorobenzenes (V) -(VIII) are synthesized. -(MAGGINI, M.; PASSUDETTI, M.; GONZALES-TRUEBA, G.; PRATO, M.; QUINTILY, U.; SCORRANO, G.; J. Org.
