## Abstract 2βSubstituted benzimidazoles have been synthesized in excellent yields under solventβfree conditions using a series of acidic ionic liquids as catalysts. The results indicate that SO~3~Hβfunctionalized ionic liquids show higher catalytic activities than other acidic ionic liquids. The e
