Used as a key reagent in organic synthesis, particularly in cross-coupling reactions such as Suzuki-Miyaura coupling, enabling the formation of carbon-carbon bonds. Its phosphonate and boronate functional groups allow dual reactivity, making it valuable in the preparation of complex organic molecules, including pharmaceuticals and agrochemicals. Commonly employed in the synthesis of bioactive compounds and conjugated systems due to its stability and selective reactivity. Also utilized in materials science for constructing functionalized aromatic frameworks in electronic materials.
