Application

This triflate ester is commonly employed in palladium-catalyzed cross-coupling reactions (e.g., Suzuki, Heck, or Stille couplings) due to its excellent leaving group properties. It serves as a key intermediate in the synthesis of complex pharmaceutical compounds and functionalized naphthalene derivatives. Researchers also utilize it for constructing electron-deficient aromatic systems in materials chemistry applications.
