چکیده
|
Sulfonic acid-functionalized pyridinium chloride ionic liquid f[pyridine- so3h]clg can effectively promote the one-pot multi-component condensation reaction between benzil, aldehydes, primary amines, and ammonium acetate under solvent-free conditions at 100°c to give the desired 1,2,4,5-tetrasubstituted imidazoles in high yields and short reaction times.
