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 applied in the synthesis of complex organic molecules, including pharmaceuticals and agrochemicals, where efficient and selective bond formation is critical. The steric bulk from the isopropyl groups helps stabilize reactive metal centers and influences the regioselectivity of transformations.
