A gold-catalyzed regioselective homodimerization of aliphatic terminal alkynes is described. Bulky and less Lewis acidic tBuXPhosAuNTf(2) is the preferred catalyst, and the additive, anhydrous NaOAc, substantially facilitates the reaction.
本文描述了一种金催化的脂肪族末端炔烃的区域选择性同二聚反应。位阻较大且路易斯酸性较弱的tBuXPhosAuNTf(2)是首选催化剂，添加剂无水醋酸钠可显著促进该反应。
