Novel fluorine-containing aromatic compound and production thereof

Abstract

Abstract NEW MATERIAL:A compound shown by formula I (Rf is 1-10C perfluoroalkyl). EXAMPLE:2,2-Bis[4-(3-amino-5-trifluoromethylphenoxy)phenyl]hexafluorop ropane. USE:A raw material for polyimide, polyamide, etc. The polymer has heat resistance, can improve water vapor resistance and reduce dielectric constant and has excellent moldability because of solvent solubility. PREPARATION:2,2-Bis(4-hydroxyphenyl)hexafluoropropane is condensed with a dinitrobenzene shown by formula II in an aprotic polar solvent (e. g. N- methylformamide) in the presence of a base (e. g. NaOH) at 100-150 deg.C to give a compound shown by formula I.
