(4-((Trimethylsilyl)ethynyl)phenyl)boronic acid is primarily used in organic synthesis, particularly in cross-coupling reactions such as the Suzuki-Miyaura reaction. This reaction is widely employed in the pharmaceutical industry to form carbon-carbon bonds, enabling the synthesis of complex organic molecules, including drug candidates. The compound’s boronic acid group acts as a key functional group for coupling with aryl halides, while the trimethylsilyl-protected ethynyl group offers versatility in further functionalization. Additionally, it serves as a building block in the development of advanced materials, such as organic semiconductors and polymers, where precise molecular architecture is crucial. Its stability and reactivity make it a valuable reagent in both academic research and industrial applications.
