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.

One Step

2-Hydroxybenzaldehydes 1a-e on reaction with malononitrile 2 in the presence of iodine as catalyst give 3-cyanocoumarins 3a-e in one step under thermal heating as well as microwave irradiations. The latter conditions are much more efficient in terms of time (2-5 minutes) and yield as compared to thermal conditions (2-2.5 hours). Following similar procedure, 3-cyano-4-methylcoumarins 3f-i have also been prepared by the reaction of 2-hydroxyacetophenones 1f-i with malononitrile 2.
