Abstract
Abstract The pinacol arylboronates can be accessed by Pd‐catalyzed borylation of arylhalides (Miyaura borylation), or by Ir‐ or Rh‐catalyzed direct borylation via aromatic CH bond activation. The article reports modified reaction conditions, under which the borylation is carried out in MeCN at 80°C without the use of BPO. In most cases, the modified reaction conditions give slightly improved yields.
