Used in organic synthesis as a boronic ester reagent for Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in the construction of biaryl and conjugated aromatic systems. Its phenanthrene moiety provides extended π-conjugation, making it valuable in the development of organic electronic materials, such as OLEDs and semiconducting polymers. The tetramethyl-substituted dioxaborolane ring enhances stability and reactivity, allowing for efficient coupling under mild conditions. Commonly employed in pharmaceutical and agrochemical research for building complex aromatic frameworks.
