Efficient, step-economic, Pd(II)-catalyzed one-pot sequential Sonogashira/Sonogashira, Sonogashira/Suzuki, Sonogashira/Heck, Suzuki/Sonogashira, Suzuki/Suzuki, Suzuki/Heck, Heck/Sonogashira, Heck/Suzuki and Heck/Heck cross coupling reactions of sterically hindered aryl/heteroaryl 1,2-dihalides have been developed. The present methodology allows the conversion of easily available aryl/heteroaryl 1,2-dihalides
高效,分步经济,Pd(II)催化的一锅式连续Sonogashira / Sonogashira,Sonogashira / Suzuki,Sonogashira / Heck,Suzuki / Sonogashira,Suzuki / Suzuki,Suzuki / Heck,Heck / Sonogashira,Heck / Suzuki和Heck /已经开发出空间受阻的芳基/杂芳基1,2-二卤化物的Heck交叉偶联反应。本方法允许在温和的反应条件下以良好至优异的产率将容易获得的芳基/杂芳基1,2-二卤化物转化为合成上有用的不对称取代的芳烃/杂芳烃。该方法学是用于构建可用于合成各种有机支架的通用底物的有力工具。
