We report herein a mild procedure for the copper‐catalyzed oxidative cross‐coupling of electron‐deficient polyfluorophenylboronate esters with terminal alkynes. This method displays good functional group tolerance and broad substrate scope, generating cross‐coupled alkynyl(fluoro)arene products in moderate to excellent yields. Thus, it represents a simple alternative to the conventional Sonogashira
我们在此报告了一种温和的程序,用于缺电子的多氟苯基硼酸酯与末端炔烃的铜催化氧化交叉偶联。该方法显示出良好的官能团耐受性和广泛的底物范围,可产生中等至优异收率的交联炔基(氟)芳烃产品。因此,它代表了常规Sonogashira反应的简单替代方案。
