Organocopper reagents from phenols: A new cobalt‐catalyzed aryl sulfonate/copper exchange reaction allows the synthesis of highly functionalized aryl copper reagents from sulfonates bearing electron‐deficient substituents under mild conditions (25–45 °C, 1–6 h; see example). Sensitive functional groups, such as aldehydes, esters, and nitriles, are well‐tolerated.
苯酚中的有机铜试剂:一种新的钴催化的芳基磺酸盐/铜交换反应可以在温和的条件下(25–45°C,1–6 h;参见示例)由带有电子缺陷取代基的磺酸盐合成高度官能化的芳基铜试剂。敏感的官能团(例如醛,酯和腈)具有良好的耐受性。
