Used as a palladium ligand precursor in catalytic cross-coupling reactions, particularly in Buchwald–Hartwig amination and Suzuki–Miyaura coupling. Enables efficient C–N and C–C bond formation under mild conditions with high turnover numbers. Shows excellent performance in the synthesis of pharmaceuticals and agrochemicals due to its electron-rich, sterically hindered structure that stabilizes active palladium species. Also applied in late-stage functionalization of complex molecules where catalyst efficiency and functional group tolerance are critical.
