Application

4-Phenoxyphenylboronic acid can be used as a reactant:
  • In the Suzuki-Miyaura coupling reaction to synthesize aryl derivatives via C-C bond formation by reacting with different aryl halides over a palladium catalyst.
  • To prepare 1-phenoxy-4-(trifluoromethyl)benzene via oxidative trifluoromethylation using Chan-Lam-type reaction conditions.
  • To synthesize evobrutinib, a potent Bruton′s tyrosine kinase (BTK) inhibitor.
