Abstract: Polyfluorochalcones react with o-phenylenediamine in ethanol and 2-propanol in the presence of triethylamine or benzyltriethylammonium chloride (TEBAC) affording polyfluorinated 2,4-diaryl-2,3-dihydrobenzo-1H-1,5-diazepines. Along with the latter in the presence of triethylamine Michael aza-adducts presumably formed, and at the use of TEBAC in 2-propanol products of intramolecular cyclization and rearrangement of benzo-1,5-diazepines, dihydrobenzimidazo[1,2-a]quinolines were obtained. The reactions of polyfluorochalcones with p-phenylenediamine in ethanol or DMF proceed mostly with the substitution of the para-fluorine atom in the perfluorophenyl rings.
