Used as a ligand in transition metal catalysis, particularly in palladium-catalyzed cross-coupling reactions. Its phosphine group coordinates effectively with metals, enhancing catalytic activity and selectivity. Commonly employed in the synthesis of fine chemicals, pharmaceuticals, and asymmetric catalysis due to its ability to stabilize metal complexes and influence stereochemical outcomes. Also utilized in the development of homogeneous catalysts where tunable electronic and steric properties are required.
