摘要:Aminodefluorination Of Tetrafluorophthalic Acid By Anhydrous Ammonia Was Shown To Give 4-Amino-3,5,6-Trifluorophthalic Acid Selectively And In A High Yield. Under The Action Of Dicyclohexylcarbodiimide This Acid Was Quantitatively Converted Into 4-Amino-3,5,6-Trifluorophthalic Anhydride,Which Is The Simplest Monomer Of The Ab-Type. The First Perfluoroaromatic Ab-Type Polyimide Was Prepared By The One-Step High-Temperature Polycondensation In A Benzoic Acid Melt And Characterized Using Ftir,NMR,Uv-Vis,Maldi Tof Ms,And Tg/dsc Methods. The Near-Ir Spectrum Of The Polyimide Exhibits No Absorption Of C-H And O-H Bond Harmonic Vibrations,Which Testifies To Considerable Promise Of Ab-Type Perfluorinated Polyimides For Optical Communication Systems.

摘要:An improved process for the preparation of 3-chloro-2,4,5-trifluorobenzoic acid is described which involves reaction of a diester of 3,4,5,6-tetrafluoro-1,2-benzenedicarboxylic acid with a substituted amine to afford 3-amino-2,4,5-trifluorobenzoic acid followed by subsequent conversion of the amio intermediate into 3-chloro-2,4,5-trifluorobenzoic acid.
