Used as a highly efficient N-heterocyclic carbene (NHC) precatalyst in organometallic catalysis, particularly in cross-coupling reactions and olefin metathesis. Its rigid chiral backbone makes it valuable in asymmetric synthesis, enabling enantioselective transformations in pharmaceutical and fine chemical manufacturing. The chloride counterion facilitates easy activation in palladium-catalyzed reactions, offering high turnover and stability under various reaction conditions.
