Potassium allyltrifluoroborate（Cat No.:L045354）is a stable, crystalline organoboron compound featuring an allyl group bonded to a trifluoroborate moiety, balanced by a potassium counterion. It serves as a versatile reagent in organic synthesis, particularly in palladium-catalyzed cross-coupling reactions such as Suzuki–Miyaura couplings. Its stability in air and moisture makes it an attractive alternative to more reactive boronic acids or esters. Potassium allyltrifluoroborate enables the efficient introduction of allyl groups into complex molecules, aiding in the synthesis of pharmaceuticals, natural products, and functionalized organic intermediates under mild and selective conditions.
