A nickel‐catalyzed three‐component reaction involving terminal alkynes, boronic acids, and alkyl halides is presented herein. Trisubstituted alkenes can be obtained in a highly regio‐ and stereocontrolled manner by the simultaneous addition of both aryl and alkyl groups across the triple bond in a radical‐mediated process. The reaction, devoid of air‐ and moisture‐sensitive organometallic reagents
本文介绍了镍催化的三组分反应,涉及末端炔烃,硼酸和卤代烷。通过在自由基介导的过程中通过三键同时添加芳基和烷基,可以以高度区域控制和立体控制的方式获得三取代烯烃。该反应不含对空气和湿气敏感的有机金属试剂和催化剂,操作简单,具有宽泛的范围和对官能团的耐受性。
