Used as a coupling reagent in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in the synthesis of complex organic molecules, particularly in pharmaceuticals and agrochemicals. Its trifluoroborate group provides enhanced stability and controlled reactivity compared to traditional boronic acids, making it suitable for late-stage functionalization and library synthesis in drug discovery. It is also employed in the preparation of substituted biaryls and heterobiaryls, which are common scaffolds in bioactive compounds.
