A new approach for the synthesis of benzimidazoles using ionogel under solvent-free conditions is reported. Catalytic activity of ionogel was compared with silica coated with ionic liquid (silica-IL) and it was found that ionogel is highly active compared to silica-IL for the synthesis of benzimidazoles. Moreover, ionogel was recyclable for the synthesis of benzimidazoles.
