Used as a key reagent in organic synthesis, particularly in cross-coupling reactions such as the Suzuki-Miyaura reaction. Its vinylboronate structure allows for the formation of carbon-carbon bonds with aryl or vinyl halides, enabling the construction of complex organic molecules. The Z-configuration of the vinyl group provides stereochemical control, making it valuable in the synthesis of natural products, pharmaceuticals, and fine chemicals where specific geometry is required. It is also employed in the preparation of conjugated systems and functionalized alkenes used in materials science and medicinal chemistry.
