Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in pharmaceutical and agrochemical synthesis. Its vinylboronate structure allows for selective coupling with aryl or vinyl halides under palladium catalysis, while the 3-bromo substituent on the propene chain enables sequential or orthogonal functionalizations, making it valuable in constructing complex organic molecules. Commonly applied in the development of conjugated systems such as styrene derivatives and functionalized alkenes. Stable and compatible with various functional groups, it supports efficient and scalable synthetic routes in research and industrial settings.
