We have unfolded a convenient and mild protocol for the synthesis of diaryl ketones via Pd‐ NHC catalysed carbonylative Suzuki coupling reaction. Notably, this method offers advantages like no use of toxic CO gas, shorter reaction time, high yield, and broad substrate scope. Several sensitive functional groups (like‐COMe, ‐COOMe, ‐F, ‐Cl, ‐Br, ‐NH2, ‐CN) are well tolerated in this reaction. In addition
我们已经展示了通过Pd-NHC催化的羰基化Suzuki偶联反应合成二芳基酮的便捷,温和的方法。值得注意的是,该方法具有以下优点:不使用有毒的CO气体,较短的反应时间,高收率和广泛的底物范围。在该反应中对几个敏感的官能团(如COMe,-COOMe,-F,-Cl,-Br,-NH 2,-CN)具有良好的耐受性。此外,我们还展示了一种新的合成生物活性和药学上重要的2-取代的3-Aroylquinolin-4(1 H)-one和acridone支架的有效途径。
