Abstract

A simple and convenient method, which proceeds through pyrylium salts, was applied for the synthesis of four new aromatic diamines based on 2,9-dimethyl[5a,10b] dihydrobenzofuro [2,3b] benzofuran. Their preparation was based on the one pot reaction of aldehydes with methyl ketones in the presence of boron trifluoride. Specially, because of aromatic structure, these diamines may be used in the synthesis of several types of heat stable polymers, such as polyamides and polyimides. 1H NMR and IR spectroscopy, as well as elemental analysis accomplished characterization of diamines. All diamines were obtained in good to excellent yields.
