Used as a ligand in transition metal catalysis, particularly in palladium-catalyzed cross-coupling reactions. Its structure allows for strong coordination to metal centers, enhancing catalyst stability and reactivity. Commonly applied in C–N and C–C bond formation reactions, such as Buchwald–Hartwig aminations and Suzuki–Miyaura couplings, where it helps achieve high yields under mild conditions. Also employed in the synthesis of pharmaceuticals and agrochemicals due to its efficiency in promoting selective transformations.
