Used as a boronic ester reagent in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in pharmaceutical and agrochemical synthesis. Its steric hindrance from the 5,5-dimethyl groups and electron-deficient aryl group (due to the trifluoromethyl substituent) enhance selectivity and stability during coupling, particularly useful in complex molecule assembly. Commonly employed in late-stage functionalization of bioactive compounds where robust and selective transmetalation is required.
