苯基三氟硼酸钾

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.

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