A highly efficient method for the synthesis of tri-aryl-substituted allenes has been developed through Cu(I)-catalyzed coupling of diaryldiazomethanes with terminal alkynes. The reaction is under mild conditions and uses simple and inexpensive CuI as the catalyst. Mechanistically, the reaction follows a pathway involving Cu(I) carbene migratory insertion.
通过Cu(I)催化的二芳基重氮甲烷与末端炔烃的偶联,已开发出一种高效的三芳基取代的丙二烯合成方法。该反应是在温和条件下,并使用简单且廉价的CuI作为催化剂。机械地,该反应如下涉及的Cu(I)卡宾洄游插入的通路。
