An efficient method for carbon–carbon bond formation is described. The process employs the palladium-catalyzed and copper-mediated cross-coupling of quinoline-2-(1H)-thiones with arylboronic acids or alkynes through C–S bond cleavage without an inert atmosphere. The method provides rapid and general access to a diverse range of 2-substituted quinolines in a single step from a wide range of quinoline-2-(1H)-thiones and arylboronic acids or alkynes.

钯催化/铜介导的喹啉-2-（1H）-硫酮的脱硫和芳基化反应，可快速获得喹啉衍生物

描述了一种有效的碳-碳键形成方法。该方法采用钯催化和铜介导的喹啉-2-（1 H）-硫酮与芳基硼酸或炔烃通过CS键断裂的无惰性气氛的交叉偶联。该方法提供了从一个范围广泛的喹啉-2-（1 H）-硫酮和芳基硼酸或炔烃中快速而通用地通过一个步骤快速地获得范围广泛的2-取代喹啉的方法。
