copper(I)-catalyzed C-O/S coupling reactions of abundant aryl bromines with related phenols or thiophenols. The key to this very discovery is the identification of an N-donor tripod ligand (DPA), and such a reaction allows the conversion of simple starting materials to complex diaryl ethers or diaryl thioethers, which are important synthetic intermediates in the preparation of bioactive molecules.
摘要 本文首次报道了 2,2'-二吡啶胺 (DPA) 作为一种新型高效的三齿配体,用于促进铜 (I) 催化的丰富芳基溴与相关酚类或苯硫酚的 CO/S 偶联反应。这一发现的关键是鉴定N-供体三脚配体 (DPA),这种反应允许将简单的起始材料转化为复杂的二芳基醚或二芳基硫醚,它们是制备生物活性分子的重要合成中间体.
