Application

4-Fluorophenylboronic acid can be used as a reactant in coupling reactions with arenediazonium tetrafluoroborates, iodonium salts, and iodanes. It is also used to make novel biologically active terphenyls.

It can also be used as a reactant in:
  • Suzuki coupling using microwave and triton B catalyst.
  • Pd-catalyzed direct arylation of pyrazoles with phenylboronic acids.
  • Mizoroki-Heck and Suzuki-Miyaura coupling reactions catalyzed by palladium nanoparticles.
  • Cu-catalyzed Petasis reactions.
  • Tandem-type Pd(II)-catalyzed oxidative Heck reaction and intramolecular C-H amidation sequence.
  • Ruthenium catalyzed direct arylation.
  • Rh-catalyzed asymmetric conjugate additions.
  • Ligand-free copper-catalyzed coupling of nitro arenes with arylboronic acids.
  • Regioselective arylation and alkynylation by Suzuki-Miyaura and Sonogashira cross-coupling reactions.
  • Suzuki cross-coupling of tetrabromothiophene.
  • Palladium-catalyzed addition to nitriles.
