Benzimidazoles are very useful building blocks for the development of molecules that are important in medicinal chemistry. 2-Substituted benzimidazole derivatives have found applications as diverse therapeutic agents, including antiulcers, antihypertensives, antivirals, antifungals, anticancers, and antihistaminics. Because of their importance, the methods for their synthesis have become a focus of Synthetic Organic Chemists. However, we failed to locate report in the literature that covers various efforts that have been made for the synthesis of 2-arylbenzimidazoles. Therefore, in the present review, we have tried to compile some of the important synthetic techniques and methodologies used for its synthesis during the last decade.

C NMR, and finally mass spectrometry. All the synthesized compounds were evaluated in vitro for their potential antibacterial activity and their preliminary safety profile was assessed through cytotoxicity assay. Additionally, six selected conjugates were evaluated for their antioxidative properties on the basis of density functional theory calculations, using radical scavenging assay (DPPH) and cellular antioxidant assay. The reported results encourage further investigation of selected compounds and are shading light on their potential pharmacological use.
