General description

4-Acetylphenylboronic acid is a boronate, belongs to a class of synthetic organic compounds. It reacts rapidly with peroxynitrite (ONOO(-)) to form stable hydroxy derivatives. It undergoes Suzuki coupling with 4-bromotriphenylamine catalyzed by dichlorobis(triphenylphosphine)Pd(II), during the synthesis of dendrimers.

Application

4-Acetylphenylboronic acid was used in the synthesis of 4′-azidoacetophenone.
Reactant involved in:
  • Palladium-catalyzed decarboxylative coupling
  • Copper-catalyzed hydroxylation
  • Palladium-catalyzed Suzuki-Miyaura cross-coupling
  • Cross-coupling with α-bromocarbonyl compounds
  • Oxidation catalyzed by Baeyer-Villiger monooxygenases
  • 1,5-substitution reactions

We report the copper(II)-catalyzed conversion of organoboron compounds into the corresponding azide derivatives. A systematic series of phenylboronic acid derivatives is evaluated to examine the importance of steric and electronic effects of the substituents on reaction yield as well as

In this study, we show that boronates, a class of synthetic organic compounds, react rapidly and stoichiometrically with peroxynitrite (ONOO(-)) to form stable hydroxy derivatives as major products. Using a stopped-flow kinetic technique, we measured the second-order rate constants for
