Anhydrous ZnCl2 Catalyzed Synthesis of 2 Aryl Substituted Benzimidazole Derivatives

Anhydrous ZnCl2 was used to be a catalyst for the synthesis of 2-arylsubstituted benzimidazoles efficiently. In this method is very simple convenient procedure, easy purification and shorter reaction time. So we prepared the many benzimidazole derivatives from this method. All the synthesized compounds were characterize d melting point, IR, 1H NMR, 13C NMR spectral data conformed the structure of the newly synthesized compounds.
