L-Proline promoted Ullmann-type reaction of vinyl bromides with imidazoles in ionic liquids

Author affiliations

Abstract

The Ullmann-type coupling reaction of vinyl bromides and imidazoles in ILs at 90–110 °C gave the corresponding N-vinylimidazoles in good to excellent yields by using L-proline as the ligand; the double bond geometry of the vinyl bromides was retained under the reaction conditions.
