Various substituted benzimidazoles were synthesized by a combination of o-phenylenediamines and aldehydes in the presence of [MOEI]-BSA with excellent yields in water and under a mild and green reaction conditions. This method is also applicable for precursors such as aromatic and unsaturated aldehydes and o-phenylenediamines. Addition of organic part to BSA and synthesis of [MOEI]-BSA as a new Bronsted acidic ionic liquid (BAIL) improved the efficiency of this catalyst. 1-Methyl-3-(2-oxyethyl)-1H-Imidazol-3-ium-Borate Sulfonic Acid ([MOEI]-BSA) was easily prepared and used as a new and highly efficient solid acid catalyst for the synthesis of benzimidazole derivatives with high isolated yields.
