Used as a key reagent in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in the synthesis of complex organic molecules. Its vinylboronate structure allows for selective coupling with aryl or vinyl halides, making it valuable in pharmaceutical and agrochemical research for building functionalized alkenes. The 6-chloro substituent on the hexenyl chain provides an additional reactive site for further derivatization, such as nucleophilic substitution or additional cross-couplings. The pinacol ester group enhances stability and handling, while the trans-configuration supports stereocontrolled synthesis. Commonly applied in the development of bioactive compounds and conjugated systems in materials science.
