  摘要：

  Syntheses of (4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)arenes through the Pd-catalyzed borylation of arylbromides with the successive use of 2,2'-bis(1,3,2-benzodioxaborole) and pinacol were investigated. PdCl2(dppf) and AcOK in EtOH or DMSO successfully provided (4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)arenes. In particular, this method was more effective in the borylation of arylbromides bearing sulfonyl groups than the conventional Pd-catalyzed borylation using pinacolborane or bis(pinacolato)diboron.

• Activation of Aryl Carboxylic Acids by Diboron Reagents towards Nickel‐Catalyzed Direct Decarbonylative Borylation

  A Ni-catalyzed direct decarbonylative borylation of aryl carboxylic acids with B2cat2 has been established. B2cat2 serves as a borylating agent, but also activates the carboxylic acid substrate towards decarbonylative coupling, playing a dual role in this reaction. A combination of experimental and computational studies reveals that the reaction proceeds through a hitherto unknown concerted decarbonylation

  已经建立了镍催化的芳基羧酸与 B 2 cat 2 的直接脱羰硼酰化反应。B 2 cat 2作为硼酸化剂，但也活化羧酸底物以进行脱羰偶联，在该反应中发挥双重作用。实验和计算研究的结合表明，该反应通过迄今为止未知的协同脱羰和还原消除步骤进行。
