Descripción

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.
