A general copper-catalyzed coupling of azoles with vinyl bromides.
A copper-catalyzed methodology for the coupling of vinyl bromides 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 vinyl bromides, and the double bond geometry of vinyl bromides is retained under the reaction conditions.
