Aplicação
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
