Used in organic synthesis as a versatile building block for creating complex molecules. It is particularly valuable in cross-coupling reactions, such as the Heck reaction, to form carbon-carbon bonds. The compound is also employed in the preparation of silicon-containing organic compounds, which are useful in materials science and pharmaceuticals. Its role in introducing vinyl groups into molecules makes it essential in the development of polymers and fine chemicals. Additionally, it serves as a precursor in the synthesis of organosilicon intermediates for further functionalization.
