Description

Potassium vinyltrifluoroborate (CAS No. 13682-77-4) is a highly versatile organoboron compound with the molecular formula C₂H₃BF₃K and the IUPAC name potassium;ethenyl(trifluoro)boranuide. This air-stable, crystalline solid is a valuable reagent in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions, where it serves as a robust vinyl transfer agent. Its trifluoroborate moiety enhances stability and solubility, making it preferable over traditional boronic acids in moisture-sensitive applications. With a purity typically exceeding 95%, this compound is rigorously tested via NMR, HPLC, and elemental analysis to ensure consistency for research and industrial use. Ideal for pharmaceutical, agrochemical, and materials science applications, it is supplied in sealed containers under inert gas to maintain integrity.

Application

Potassium vinyltrifluoroborate is widely used in palladium-catalyzed cross-coupling reactions to introduce vinyl groups into aromatic or heteroaromatic systems, enabling the synthesis of styrenes and conjugated polymers. Its stability under aqueous conditions makes it suitable for one-pot multicomponent reactions in drug discovery. Additionally, it serves as a key intermediate in the preparation of fluorinated organic compounds for agrochemical and material science research.
