  cooperative catalysis, also known as the Catellani reaction, has become an increasingly useful method for site-selective arene functionalization; however, certain constraints still exist because of its intrinsic mechanistic pathway. Herein, we report a redox-neutral ortho functionalization of aryl boroxines via Pd/NBE catalysis. An electrophile, such as carboxylic acid anhydrides or O-benzoyl hydroxylamines,

  钯/降冰片烯（Pd / NBE）协同催化，也称为Catellani反应，已成为位点选择性芳烃官能化的一种越来越有用的方法。但是，由于其固有的机理途径，仍然存在某些限制。在这里，我们报告通过Pd / NBE催化的芳基硼氧烷的氧化还原中性邻位官能化。亲电子试剂，例如羧酸酐或O-苯甲酰基羟胺，在环硼氧烷邻位偶联，质子作为第二种亲电子试剂引入ipso位置。该反应不需要额外的氧化剂或还原剂，并且避免了化学计量的碱或酸，从而可以耐受各种官能团。特别地，证明了芳基碘和环硼氧烷部分之间的正交化学选择性，其可用于控制反应序列。最后，氘标记研究支持ipso质子化途径。这种独特的机械特性可能会激发新型Pd / NBE催化的转化的发展。

  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。
