Application

3-Cyanophenylboronic acid pinacol ester can be used as a reactant to synthesize:
  • 3-Cyano aryl/ heteroaryl derivatives by forming a C−C bond via palladium-catalyzed Suzuki-Miyaura reaction.
  • 3-(Phenylamino)benzonitrile by copper-catalyzed Chan-Evans-Lam amination reaction.
  • 3-(Trifluoromethyl)benzonitrile using potassium (trifluoromethyl)trimethoxyborate.
