This (Z)-configured alkenylboronic acid pinacol ester is primarily utilized in organic synthesis as a reagent for cross-coupling reactions, notably the Suzuki-Miyaura reaction. It facilitates the stereospecific transfer of the (Z)-but-2-en-1-yl group to form carbon-carbon bonds with aryl or vinyl halides, enabling the efficient assembly of complex organic molecules in pharmaceutical, agrochemical, and fine chemical applications. The compound's stability under diverse reaction conditions also supports its use in materials science for incorporating alkenyl functionalities into polymers and other advanced structures.
