应用
Potassium trans-beta-styryltrifluoroborate is used as a reactant for Suzuki-Miyaura cross-coupling, in enantioselective total synthesis of naseseazines A and B via regioselective Friedel-Crafts based arylative dimerization, in metal-free chlorodeboronation reactions, in preparation of aryl ketones via Lewis acid-catalyzed nucleophilic substitution and in preparation of Weinreb amides by palladium-catalyzed cross-coupling reactions.

备注
Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Incompatible with strong oxidizing agents.
