A simple and eco-friendly protocol for the synthesis of substituted 2-arylbenzimidazoles is described. In this process, 2-arylbenzimidazoles were prepared in the presence of a newly introduced ionic liquid prolinium nitrate [Pro]NO3 as catalyst, under solvent-free condition. This process was performed under mild condition without using any oxidant with good to excellent yields and remarkable chemoselectivity in the absence of any byproduct. The ionic liquid can be recovered easily and reused.
Very fast and efficient synthesis of some novel substituted 2-arylbenzimidazoles in water using ZrOCl2?nH2O on montmorillonite K10 as catalyst

A simple and eco-friendly protocol for the synthesis of some novel substituted 2-arylbenzimidazoles was developed. In this process, these compounds were prepared in water as the solvent using ZrOCl2?nH 2O supported on montmorillonite K10 as an efficient water tolerating Lewis acid. The reaction was performed under mild conditions with good to excellent yields and remarkable chemoselectivity in the absence of any byproduct.
