Used as a key reagent in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in complex organic synthesis. Its boronic ester functionality allows for selective coupling with aryl or vinyl halides under mild conditions, making it valuable in pharmaceutical and agrochemical development. The Z-configuration provides stereochemical control in the synthesis of olefin-containing target molecules. Commonly employed in late-stage functionalization due to its stability and reactivity profile.
