Used as a key reagent in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds between aromatic systems. Its alkyne-functionalized structure allows for the introduction of phenylacetylene moieties into target molecules, making it valuable in the synthesis of conjugated organic materials such as OLEDs, organic semiconductors, and pharmaceutical intermediates. The borolane group provides high stability and reactivity under mild conditions, facilitating efficient coupling with aryl halides in the presence of palladium catalysts. Commonly employed in research and development of advanced organic electronic materials and complex molecular architectures.
