[ 1 ] - Zwitterionic imidazolium salt of [MOEI]-BSA: An efficient solid acid catalyst-promoted green synthesis of quinoxaline derivatives

Easily synthesized1-methyl-3-(2-oxyethyl)-1H-imidazol-3-ium-borate sulfonic acid {[MOEI]-BSA} as a novel catalyst efficiently promoted the synthesis of quinoxaline derivatives via condensation of various diamines with 1,2-dicarbonyl compounds at room temperature conditions in ethanol. This research provides a new method for the synthesis of quinoxalines in good to excellent yields with little c...

[ 2 ] - Catalytic application of an organosuperbase denderon grafted on mesoporous SBA-15 and related palladium complex in the aerobic oxidation of alcohols

An efficient synthetic method for successful synthesis of amine denderon on SBA-15 and related Pd (II) complex has been developed. This modified mesoporous material was characterized by various techniques such as TEM, XRD, atomic absorption spectroscopy, N2 adsorption-desorption, and FT-IR. The catalytic activities of the prepared catalysts were investigated by employing aerobic oxidation of al...

[ 3 ] - One-pot synthesis of highly regioselective β-azido alcohols catalyzed by Brønsted acidic ionic liquids

In this protocol, 3-(2-carboxybenzoyl)-1-methyl-1H-imidazol-3-ium chloride [Cbmim]Cl and sulfonic acid functionalized pyridinium chloride [pyridine-SO3H]Cl as a new, reusable, and green Brønsted acidic ionic liquid (BAIL) catalyst were synthesized and successfully used for the one-pot ring opening of epoxide with sodium azide (NaN3) in water at room temperature. Epoxides under ring-opening easi...

[ 4 ] - An efficient facile and one-pot synthesis of 2-arylsubstituted benzimidazole derivatives using 1-methyl-3-(2-oxyethyl)-1H-imidazol-3-ium-borate sulfonic acid as a recyclable and highly efficient ionic liquid catalyst at green condition

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. Various substituted benzimidazoles were synthesized by a combination of o-phenylenediamines and aldehydes in the presence of [MOEI]-BSA with excellent yields in water a...
