Used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions to construct conjugated systems for pharmaceuticals and organic electronic materials. Serves as a key intermediate in the preparation of advanced intermediates for drug discovery and functional polymers. The boronate ester group enables efficient carbon-carbon bond formation under mild conditions, making it valuable in the development of complex organic molecules. Commonly employed in research settings for the synthesis of biaryl compounds and conjugated olefins with high stereoselectivity.
