We describe a copper‐catalyzed Sonogashira coupling reaction of alkyl halides with terminal alkynes under ambient conditions, efficiently providing a versatile tool for the construction of substituted alkynes. A new proline‐based N,N,P‐ligand is utilized to promote the transformation under a mild reaction condition. Diverse alkyl halides, such as primary and secondary (hetero)benzyl chlorides and bromides
我们描述了在环境条件下烷基卤化物与末端炔烃的铜催化Sonogashira偶联反应,为构建取代炔烃提供了有效的工具。一种新的基于脯氨酸的N,N,P-配体用于在温和的反应条件下促进转化。不同的烷基卤化物,例如伯和仲(杂)苄基氯和溴化物,仲和叔α-溴酰胺和炔丙基溴,可用于提供各种炔烃。
