A copper-catalyzed methodology for the coupling of vinylbromides with azoles has been developed. This protocol uses a combination of 10 mol % of copper iodide and 20 mol % of ethylenediamine as catalyst. The reaction proceeds with various azoles and vinylbromides, and the double bond geometry of vinylbromides is retained under the reaction conditions.
