애플리케이션

3,4-Difluorophenylboronic acid can be used as a reactant to prepare:
  • Fluorinated biaryl derivatives via Suzuki cross-coupling reaction with aryl and heteroaryl halides.
  • Flurodiarylmethanols by reacting with aryl aldehydes using Ni catalyst.
  • Conjugated fluorodiazaborinines by treating with diamines via intermolecular dehydration reaction for the detection of explosives.

Reactant involved in:
  • Suzuki cross-coupling reactions with aryl and heteroaryl halides
  • Oxo directing Liebeskind-Srogl cross-coupling reactions with gem-dihaloolefin-type α-oxo ketene dithioacetals
  • Substitution reactions with enyne acetates and carbonates
