Application
Diphenyl 2-pyridyl phosphine is primarily used as a ligand in transition metal complexes for various catalytic processes. It appears as a yellow to orange crystalline powder and plays a critical role in facilitating a range of palladium-catalyzed reactions. These include the distannylation and disilylation of ortho-quinodimethanes, enabling the synthesis of complex disilacarbocycles, as well as the alkoxycarbonylation of allenes. Moreover, it serves as a versatile ligand in other metal-catalyzed carbonylations, hydrations, dehydrogenative couplings, carbostannylations, and silylations. Additionally, it is employed as a reagent in the Mitsunobu reaction, demonstrating its broad utility in synthetic organic chemistry.
