Used as a ligand precursor in homogeneous catalysis, particularly in palladium-catalyzed cross-coupling reactions such as Suzuki-Miyaura and Heck reactions. Its steric bulk and electron-donating properties enhance catalyst stability and selectivity. Also employed in the synthesis of phosphine-based ligands for transition metal complexes in organic synthesis and pharmaceutical manufacturing. Shows utility in materials science for tuning the electronic properties of metal-organic frameworks and luminescent complexes.
