Widely used as a bidentate ligand in organometallic chemistry and homogeneous catalysis. Its strong electron-donating properties make it ideal for stabilizing low-oxidation-state metal centers in catalysts. Commonly employed in palladium- and nickel-catalyzed cross-coupling reactions, enhancing catalytic activity and selectivity. Also used in hydrogenation and hydroformylation processes due to its ability to modulate metal reactivity and improve catalyst longevity. The steric bulk from the di-i-propyl groups helps prevent unwanted side reactions, making it valuable in fine chemical and pharmaceutical synthesis.
