Used as a key intermediate in organic synthesis, particularly in transition metal-catalyzed cross-coupling reactions. Its vinyl triflate functionality enables palladium-catalyzed reactions such as Stille, Suzuki, and Heck couplings, allowing the formation of carbon-carbon bonds. Commonly employed in the synthesis of complex cyclic compounds and seven-membered ring systems found in bioactive molecules. Its strained cycloheptene ring adds unique reactivity, making it valuable in the development of pharmaceuticals and specialty organic materials.
