Two new arylene diamines compounds have been synthesized via palladium catalyzed reaction of 1,4–phenylenediamine with two aromatic dibromides. This one–pot reaction was based on using the catalyzed system resulting from Pd \ BINAP, Pd \ di–t–butylphosphinobiphenyl, Pd \ P(t–Bu)3, Pd \1,3–bis(2,6– diisopropylphenyl)imidazolium chloride. MS, 1H–NMR and FT–IR spectroscopy, as well as elemental analysis accomplished characterization of aryl diamines. All arylene diamines were obtained in good to excellent yields. Specially, because of aromatic structure, these diamines may be considered as potential monomers in the synthesis of several types of heat stable polymers, such as polyamides and polyimides.
