Abstract
2,4,5-Trisubstituted imidazoles have been synthesized in excellent yields (85–95%) in the presence of 5 mol% of [(CH2)4SO3HMIM][HSO4] as a Brønsted acidic ionic liquid.
Notes
Note. All the compounds in Table were characterized on the basis of 1H NMR and IR spectral data, which were consistent with those of reported in literature.
