that the palladium-catalyzed cross-coupling reaction of air-stable potassium alkenyltrifluoroborates with aryl halides and triflates proceeds readily with good yields. Recent progress in outlining the scope and limitations of such reactions is described herein. The palladium-catalyzed cross-coupling reaction of potassium alkenyltrifluoroborates with aryl and heteroaryl halides and triflates proceeds
我们以前曾报道过,空气稳定的链烯基三氟硼酸钾与芳基卤化物和三氟甲磺酸酯的钯催化交叉偶联反应容易进行,收率很高。本文描述了概述此类反应的范围和局限性的最新进展。链烯基三氟硼酸钾与芳基和杂芳基卤化物和三氟甲磺酸酯的钯催化交叉偶联反应易于进行,产率中等至优异。烯基的交叉偶联反应通常可以在叔丁基NH 2作为碱的存在下,在i-PrOH-H 2 O中使用2mol%的PdCl 2(dppf).CH 2 Cl 2作为催化剂来进行。两种配偶体均容忍多种官能团,并且该方法对于烯基三氟硼酸酯原料是立体定向的。
