Used in organic synthesis as a building block for Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in pharmaceuticals and agrochemicals. Its vinylboronic acid structure allows for selective coupling with aryl or vinyl halides, making it valuable in creating complex organic molecules. Commonly applied in the development of conjugated systems such as those found in functional materials and bioactive compounds. The (E)-configuration ensures stereochemical control during synthesis, which is critical for achieving desired biological activity in target molecules.
