Used as a specialized intermediate in organic synthesis, particularly in the preparation of functionalized cyclopentadiene derivatives for catalysis and materials science. Its silyl-protected exocyclic methylene group allows controlled reactivity in cross-coupling reactions and cycloadditions. Commonly employed in the development of ligands for transition metal catalysts, especially in olefin metathesis and polymerization processes. The ester groups enable further derivatization, making it valuable in constructing complex molecular architectures for pharmaceuticals and advanced polymers.
