Alkynyl amides were synthesized from a palladium-catalyzed coupling reaction of alkynyl carboxylic acids and amines under carbon monoxide. The reaction was conducted with palladium(II) acetate (5 mol-%) and silver(I) oxide (1.0 equiv.) in acetonitrile at 80 °C for 1 h. This method provides good to moderate product yields and good functional group tolerance towards ketone, ester, and nitrile groups.
炔基酰胺是通过钯催化的炔基羧酸和胺在一氧化碳下的偶联反应合成的。反应用乙酸钯 (II) (5 mol-%) 和氧化银 (I) (1.0 当量) 在乙腈中在 80 °C 下进行 1 小时。该方法提供了良好到中等的产品收率以及对酮、酯和腈基团的良好官能团耐受性。
