Description
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.
