Used as a specialized ligand in palladium-catalyzed cross-coupling reactions, particularly in Suzuki-Miyaura and Buchwald-Hartwig aminations. Its sterically hindered, electron-rich structure enhances catalytic efficiency and stabilizes metal centers, enabling reactions with challenging substrates such as aryl chlorides or sterically encumbered partners. Commonly applied in pharmaceutical synthesis and materials science where high selectivity and yield are critical. Also employed in the development of novel catalysts for asymmetric synthesis due to its rigid, chiral backbone.
