Used as a bifunctional coupling reagent in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions. The compound enables the sequential or selective formation of carbon-carbon bonds due to its two boronic ester groups, one of which can be selectively activated. It is valuable for constructing conjugated diene systems and polyene frameworks found in natural products and pharmaceuticals. Its (E)-configuration ensures stereochemical control in the resulting olefinic products. Commonly employed in the synthesis of complex molecules such as bioactive compounds and functional materials where precise molecular geometry is required.
