Potassium vinyltrifluoroborate(CAT: R020307) is a stable, crystalline organoboron reagent widely used in cross-coupling reactions, particularly Suzuki–Miyaura couplings. Featuring a vinyl group bonded to a trifluoroborate anion and balanced by a potassium cation, it offers excellent stability under ambient conditions and is easily handled in synthetic workflows. Its high reactivity under palladium-catalyzed conditions enables the efficient formation of carbon–carbon bonds, making it valuable in the synthesis of alkenes, pharmaceutical intermediates, and complex organic molecules. The compound’s water-tolerant nature and compatibility with a range of functional groups support its use in medicinal chemistry, agrochemical development, and materials science research.
