Herein, we report the first solid-state protocol for nickel(0)-mediated Yamamoto-coupling reactions using ball milling. A variety of aryl halides reacted efficiently in the presence of bis(cyclooctadiene)nickel(0) [Ni(cod)2] and 4,4'-di-tert-butyl-2,2'-bipyridyl under solid-state mechanochemical conditions, affording the corresponding biaryls in high yields. Considering that potentially harmful and
摘要 在此,我们报告了第一个使用球磨进行镍 (0) 介导的 Yamamoto 偶联反应的固态方案。多种芳基卤化物在双(环辛二烯)镍(0)[Ni(cod)2]和4,4'-二叔丁基-2,2'-联吡啶存在下在固态机械化学条件下有效反应,以高产率提供相应的联芳基。考虑到不需要潜在有害的高沸点有机溶剂,本研究为传统的基于溶液的山本偶联提供了一种更方便、更环保、更可持续的替代方案。还描述了固态山本偶联聚合和催化变体的开发。
