Used as a key intermediate in cross-coupling reactions, particularly in palladium-catalyzed transformations such as Suzuki-Miyaura and Stille couplings. Its triflate group acts as an excellent leaving group, enabling efficient formation of carbon-carbon bonds in the synthesis of complex organic molecules, including pharmaceuticals and agrochemicals. The trimethylsilyl group can be selectively removed or further functionalized, adding versatility in multi-step synthetic routes. Commonly employed in the preparation of pyridine-based compounds where controlled substitution is required.
