Used as a ligand in transition metal catalysis, particularly in palladium-catalyzed cross-coupling reactions. Its steric bulk and electron-donating properties enhance catalyst stability and selectivity. Commonly employed in the development of N-heterocyclic carbene (NHC) precursors for organometallic complexes. Also applied in materials science for synthesizing functionalized polymers and optoelectronic materials due to its stable aromatic framework.
