Widely used as a ligand in homogeneous catalysis, particularly in transition metal-catalyzed reactions such as hydroformylation, hydrogenation, and cross-coupling reactions. Its primary role is to coordinate with metals like rhodium, palladium, or ruthenium, enhancing catalytic activity, selectivity, and stability. The primary amine group allows for further functionalization or immobilization on supports, making it useful in designing supported catalysts or creating tailored catalytic systems. It is also employed in the synthesis of more complex phosphine ligands and in materials science for modifying surface properties of nanoparticles. Its bifunctional nature (phosphine and amine groups) enables dual coordination or participation in cooperative catalysis.
