Description
This bidentate phosphine ligand features two diphenylphosphino groups positioned ortho to the biphenyl linkage, enabling robust coordination to transition metals. Its rigid, electron-rich architecture enhances catalytic activity in palladium- and nickel-catalyzed cross-coupling reactions, offering improved stability and selectivity under standard conditions.
Application
2,2'-Bis(diphenylphosphino)-1,1'-biphenyl serves as a versatile, bench-stable ligand in transition metal catalysis, enabling efficient cross-coupling reactions and palladium-catalyzed transformations. Its rigid biphenyl backbone and orthogonal phosphine groups provide strong metal coordination, enhancing catalyst activity and selectivity in Suzuki-Miyaura, Stille, and Negishi couplings. Ideal for complex molecule synthesis, it offers excellent functional group tolerance and ease of purification in industrial and academic settings.
