Abstract
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.
Keywords: 2-Arylbenzimidazoles, Methodologies, Synthetic routes, o-phenylenediamine.

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
