Used as a ligand in transition metal catalysis, particularly in palladium-catalyzed cross-coupling reactions. Its phosphine group coordinates well with metals, enhancing catalytic activity and stability. Commonly applied in Suzuki and Heck reactions for forming carbon-carbon bonds in organic synthesis. The bulky triphenyl structure helps control selectivity and prevents catalyst deactivation. Also employed in the development of homogeneous catalysts for industrial and pharmaceutical processes where high efficiency and specificity are required.
