This compound is primarily used in organic synthesis, particularly in cross-coupling reactions such as the Suzuki-Miyaura reaction. Its boronate ester group makes it a valuable intermediate for constructing complex organic molecules, especially in the pharmaceutical and materials science fields. The phenylethynyl group allows for further functionalization, enabling the creation of conjugated systems, which are essential in developing organic electronic materials like OLEDs and semiconductors. Additionally, the trimethylsilyl group provides stability and can be selectively removed or transformed, offering versatility in synthetic pathways.
