Abstract

2-substituted benzimidazoles have been synthesized in a single pot from aromatic aldehydes and ophenylenediamine catalyzed by FeCl3/Al2O3 in DMF under ultrasonic irradiation and afforded good yields in a short period of time.

Keywords: Aromatic aldehydes, benzimidazoles, FeCl3/Al2O3, o-phenylenediamine, ultrasonic, influenza, o-aryldiamines, benzoquinone, nitrobenzene, tetracyanoethylene
