4-(Trifluoromethyl)phenylboronic acid can be used as a reactant in:
  • Site-selective Suzuki-Miyaura cross-coupling reactions.
  • Palladium-catalyzed direct arylation reactions.
  • Tandem-type Pd(II)-catalyzed oxidative Heck reaction and intramolecular C-H amidation sequence.
  • Ruthenium catalyzed direct arylation.
  • Ligand-free copper-catalyzed coupling reactions.
  • Amination and conjugate addition reactions.
  • Regioselective arylation and alkynylation by Suzuki-Miyaura and Sonogashira cross-coupling reactions.
  • Rhodium-catalyzed asymmetric 1,4-addition reactions.
  • Copper-catalyzed nitration reactions.
  • Regioselective Suzuki-Miyaura coupling and tandem palladium-catalyzed intramolecular aminocarbonylation and annulation.
  • Palladium catalyzed allylation reaction with allyl alcohols.
  • N-Arylation of imidazoles and amines in the presence of copper-exchanged fluorapatite as a catalyst.

It can also be used as a reactant to prepare:
