Used primarily in organic synthesis as a bifunctional coupling reagent, enabling the introduction of both boron and silicon-based functional groups into target molecules. The vinyl linker allows for further modification via cross-coupling reactions or functional group interconversion. Commonly employed in the preparation of complex organic molecules, including pharmaceuticals and advanced materials, where selective protection and subsequent coupling are required. The tert-butyldimethylsilyl (TBS) group acts as a protecting group for alcohols, while the boronate ester enables Suzuki-Miyaura cross-coupling, making this compound valuable in multi-step synthetic strategies. Also utilized in the development of conjugated systems for optoelectronic materials.
