【Application】 A bulky electron-donating phosphine ligand widely used in palladium-catalyzed cross-coupling reactions, including Suzuki-Miyaura, Heck, Negishi, Sonogashira, Stille, Hiyama, and Buchwald-Hartwig amination. Also serves as a ligand in nickel-catalyzed C(sp⊃2;)-N cross-couplings and as a precursor for synthesizing transition metal catalysts for olefin metathesis. Additionally, used in the synthesis of coordination complexes with luminescent or magnetic properties for materials science and pharmaceutical research.
