Used as a key intermediate in organic synthesis, particularly in the preparation of complex molecules through palladium-catalyzed coupling reactions. Its vinyl bromide functionality allows it to participate in cross-coupling reactions such as Suzuki or Heck reactions, enabling the construction of carbon-carbon bonds. The tert-butyl ester group provides stability and can be easily deprotected under mild acidic conditions to reveal the corresponding carboxylic acid, making it valuable in multi-step synthesis of pharmaceuticals and natural products. Its structure also lends itself to use in ring-closing metathesis reactions, where the terminal alkene is utilized to form cyclic frameworks. Commonly employed in the development of bioactive compounds and functionalized polymers.
