Used as a precursor for generating N-heterocyclic carbenes (NHCs), particularly in catalytic applications. Its bulky t-butyl groups enhance steric protection, making the derived carbene suitable for stabilizing reactive metal centers in homogeneous catalysis. Commonly employed in palladium-catalyzed cross-coupling reactions, such as Suzuki and Heck reactions, where it improves catalyst longevity and activity. Also utilized in organocatalysis for promoting carbon–carbon and carbon–heteroatom bond formations. The chloride counterion facilitates easy salt metathesis, allowing incorporation into various catalytic systems.
