A simple and practical procedure for the synthesis of 2-arylbenzimidazoles through a one-pot condensation reaction
of o-phenylenediamine and various aromatic aldehydes in the presence of nano-Copper Y Zeolite (NCZ) as a catalyst
in ethanol at room temperature has been described. The CuY Zeolite nanocatalyst was characterized with SEM image.
Some of the major advantages of this practical procedure are use of available safe and reusable catalyst, high yields, short
reaction time and easy and quick isolation of the product.
Keywords: Benzimidazole, Catalyst, Aryl aldehyde, Transition nano metal zeolite.
