Synergetic catalytic effect of ionic liquids and ZnO nanoparticles on the selective synthesis of 1,2-disubstituted benzimidazoles using a ball-milling technique

Abstract

A solvent-free selective synthesis of 1,2-disubstituted benzimidazoles was developed in the presence of recyclable ionic liquid-coated ZnO-nanoparticles using a ball-milling technique.
