Used as a reagent in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in organic synthesis. Its stability and solubility make it suitable for coupling with aryl and heteroaryl halides to produce biaryl compounds, which are important in pharmaceuticals, agrochemicals, and materials science. The trifluoroborate group acts as a masked boronic acid, offering improved handling and reduced toxicity compared to boronic acids. Commonly applied in the synthesis of complex molecules where controlled reactivity and functional group tolerance are required.
