Descripción general

Phenylboronic acid is a highly stable receptor ligand used in cross-coupling reactions and drug delivery.

Phenylboronic acid (PBA) is an organoboronic acid. It behaves as a molecular receptor that can attach to compounds containing cis-diol group. Microwave-assisted Suzuki coupling of aryl chlorides with phenylboronic acid in the presence of Pd/C (catalyst) and water (solvent) has been described. Palladium-catalyzed cross-coupling reaction of phenylboronicacid with haloarenes to afford biaryls has been reported.

Aplicación

Phenylboronic acid may be employed in the following reactions:
  • Rhodium-catalyzed intramolecular amination.
  • Pd-catalyzed direct arylation.
  • Mizoroki-Heck and Suzuki-Miyaura coupling reactions catalyzed by palladium nanoparticles.
  • Palladium-catalyzed stereoselective Heck-type reaction.
  • Highly effective Palladium-catalyzed arylation Suzuki-Miyaura cross-coupling in water.

Phenylboronic acid may be employed as reagent in the preparation of:
  • Ni(II) pincer complex and Pd(II) pyridoxal hydrazone metallacycles as catalysts for the Suzuki-Miyaura cross-coupling reactions.
  • N-type polymers for all-polymer solar cells.
  • Novel series of potent and selective mTOR kinase inhibitors.
  • Inhibitors of lactate dehydrogenase against cancer cell proliferation.

Phenylboronic acid (PBA)-functionalized materials have attracted considerable attention because of their potential applications in many fields. In this paper, we report a PBA-segregated honeycomb-patterned porous film (HPPF) for glucose sensing. Polystyrene-block-poly(acrylic acid-co-acrylamidophenylboronic acid) with different contents of PBA pendants was
