Used as a chiral N-heterocyclic carbene (NHC) precursor in asymmetric catalysis. It plays a key role in enantioselective transformations such as hydrogenation, cyclopropanation, and C–C bond formation reactions. The ligand derived from this salt enhances stereoselectivity when coordinated to transition metals like ruthenium, rhodium, or palladium. Commonly applied in pharmaceutical synthesis and fine chemicals where high enantiomeric purity is required. Its steric bulk and electron-donating properties improve catalyst stability and selectivity under mild reaction conditions.
