Used as a highly efficient chiral ligand in asymmetric catalysis, particularly in palladium-catalyzed cross-coupling reactions and rhodium-catalyzed asymmetric hydrogenation. Its sterically hindered, electron-rich structure enhances enantioselectivity and catalytic activity, making it valuable in the synthesis of chiral pharmaceuticals and fine chemicals. The trimethylsilyl groups improve solubility in nonpolar solvents and contribute to air and moisture stability, facilitating handling and storage. Commonly applied in the production of enantiomerically pure intermediates for drugs and agrochemicals.
