off-white to beige crystalline powder??? ??
4-Chlorophenylboronic acid is white or off-white crystalline powder. It has certain solubility in water and is soluble in strong polar organic solvents such as dimethyl sulfoxide, but insoluble in ether solvents. It has similar chemical properties to phenylboronic acid.??
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.
