method devoted to the direct conjugate addition of functionalized aryl compounds onto Michael acceptors is described. The CoBr2(2,2‘-bipyridine) complex appears to be an extremely suitable catalyst for the activation of a variety of aromatic reagents ranging from halides to triflates functionalized by reactive groups. This procedure allows for the synthesis of compounds resulting from 1,4-addition in good
描述了致力于将官能化的芳基化合物直接共轭加成到迈克尔受体上的有效的钴催化方法。CoBr 2(2,2'-联吡啶)配合物似乎是一种非常合适的催化剂,可用于活化各种芳族试剂,从卤化物到被反应基团官能化的三氟甲磺酸酯。该方法允许以良好的至优异的产率合成由1,4-加成产生的化合物。该原始方法的多功能性代表了使用有机金属试剂的大多数已知方法的简单替代方案。
