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.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
