Used as a key reagent in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in pharmaceutical and agrochemical synthesis. Its arylboron structure facilitates efficient coupling with aryl halides under palladium catalysis, making it valuable in the preparation of complex organic molecules, particularly in drug discovery and materials science. The electron-withdrawing trifluoromethoxy group enhances reactivity and stability, improving coupling efficiency in demanding synthetic routes.
