Abstract

A facile and green protocol has been developed for the synthesis of 2-aryl-1,3-benzimidazole derivatives using ZnO nanoparticles as reusable catalyst. The reactions are very fast, high yielding and the nano-catalyst was recycled for ten times. In this paper we have reported the synthesis of 2-aryl-1,3-benzimidazole derivatives from aromatic aldehydes (containing electron donating group like, -OMe, -Me etc. and electron withdrawing group like, -NO2, etc.) and 1,2-phenyl-diamine.We have synthesized a series of 2-aryl-1,3-benzimidazoles with various 5- and 6-position substituent (-H, -OCH3, -CH3, -OH, -Cl, -Br, -NO2, ) derivatives.
