In a copper-catalyzed decarboxylative coupling reaction, a broad range of aryl, alkenyl, alkynyl, and alkyl substituted 1,1-dibromo-1-alkenes react smoothly with aryl and alkyl substituted potassium propiolates to produce unsymmetrical 1,3-diynes and 1,3,5-triynes with high selectivity and good functional group compatibility.
