Application

4-Chlorophenylboronic acid can be used as a reactant in:
  • Palladium-catalyzed direct arylation.
  • Cyclopalladation.
  • Tandem-type Pd(II)-catalyzed oxidative Heck reaction and intramolecular C-H amidation.
  • Copper-mediated ligandless aerobic fluoroalkylation.
  • Pd-catalyzed arylative cyclization.
  • Ruthenium catalyzed direct arylation.
  • Ligand-free copper-catalyzed coupling reactions.
  • Regioselective arylation and alkynylation by Suzuki-Miyaura and Sonogashira cross-coupling reactions.

It can also be used to prepare:
  • Substituted diarylmethylidenefluorenes via Suzuki coupling reaction.
  • Baclofen lactam by Suzuki coupling of a pyrrolinyl tosylate, followed by hydrogenation reaction.
  • Palladium(II) thiocarboxamide complexes as Suzuki coupling catalysts.
  • Biaryls by Suzuki reactions of aryl chlorides, bromides, and iodides with arylboronic acids.
