Applications
Aryltrifluoroborate salts are more nucleophilic than the corresponding arylboronic acids and undergo ligand-free Pd-catalyzed cross-coupling reactions with arenediazonium tetrafluoroborates to give good yields of biaryls. Suzuki Cross-Coupling are conducted using organotrifluoroborates as a potent boronic acid surrogates. In the presence of Dicarbonyl­(2,4-pentanedionato)­rhodium(I)­, 39295, K aryl- and alkenyltrifluoroborates add to aldehydes and enones to give secondary alcohols and saturated ketones, respectively.

Solubility
Soluble in water.

Notes
Store in cool dry conditions in well sealed containers. Incompatible with strong oxidizing agents.
