The ionic liquid 1-methyl-3-(3-sulfopropyl)imidazolium chloride ([MIMPs]+Cl-) in combination with 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) and sodium nitrite (NaNO2) as a catalytic system demonstrates high efficiency in the one-pot two-step aerobic oxidative condensation of benzyl alcohols with 1,2-phenylenediamines to give benzimidazoles. Various benzimidazoles are obtained in good to excellent yields by this strategy.

AbstractConversion of lignocellulose into useful chemicals is an important research topic in the area of biomass utilization. In this study, microcrystalline cellulose (MC) was dissolved in a mixed-solvent system containing the ionic liquid (IL) 1-allyl-3-methylimidazolium chloride ([Amim]Cl) andN-methyl-pyrrolidone (NMP), and the cellulose was directly converted into methyl glucoside (MG) by acid-catalyzed methanolysis aided by microwave irradiation (μWIr). Under moderate reaction temperature and pressure, and in the presence of acetyl chloride/methanol (in situformed HCl) as an acid catalyst, MG was obtained in a 42% yield. In contrast, in the absence of either IL or μWIr, the MG yield was only 5 or 21%, respectively. Both μWIr and the dissolution of cellulose in IL were quite effective for the conversion of cellulose into MG.
