• <scp>Pd‐Catalyzed Site‐Selective</scp> Borylation of Simple Arenes <i>via</i> Thianthrenation ^†
  作者：Xiao‐Yue Chen、Yu‐Hao Huang、Jian Zhou、Peng Wang

  DOI：10.1002/cjoc.202000212

  日期：2020.11

  Site‐selective borylation of simple arenes was realized in one pot via an electrophilic thianthrenation/Pd‐catalyzed borylation sequence. The key to achieve this operatically simple process is the use of Pd catalysis, which could tolerate the solvent and acidic conditions used in the thianthrenation step. This protocol features mild conditions, broad functional group tolerance, and simple manipulations

  日期：2010.3.1

  Leave the metal out: Arylboronates are produced in moderate to good yields by direct borylation of readily available aryl amines (see scheme). The reaction can be carried out under air at room temperature and transition‐metal catalysis is not required. The boronate products can be used without purification in Suzuki–Miyaura cross‐coupling reactions.
