Used as a key intermediate in organic synthesis, particularly in palladium-catalyzed cross-coupling reactions such as the Suzuki-Miyaura and Heck reactions. Its primary application lies in the construction of complex aromatic and conjugated systems, especially in the development of pharmaceuticals, agrochemicals, and advanced materials. The triflate group acts as an excellent leaving group, enabling efficient carbon-carbon bond formation. The trimethylsilyl group can be selectively removed or further functionalized, offering versatility in multi-step syntheses. Commonly employed in the preparation of naphthalene-based derivatives used in optoelectronic materials and liquid crystals.
