Widely 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-forming reactions. The compound’s bulky chiral groups help induce high stereoselectivity when coordinated to transition metals like ruthenium, rhodium, or palladium. Commonly applied in pharmaceutical synthesis and fine chemical manufacturing where control over stereochemistry is critical. Its tetrafluoroborate salt form enhances stability and handling in air-sensitive reactions.
