Bis[2-[(oxo)diphenylphosphino]phenyl] ether（Cat No.:L024587）is a bidentate organophosphorus ligand featuring two diphenylphosphine oxide groups attached to a central ether-linked biphenyl framework. Its rigid, symmetrical structure and electron-withdrawing phosphine oxide functionalities make it an effective ligand in coordination and organometallic chemistry. This compound is often employed in catalysis, including transition metal-catalyzed cross-coupling, hydrogenation, and asymmetric synthesis. The ether linkage offers flexibility, while the phosphine oxide groups enhance solubility and metal-binding strength. It serves as a versatile scaffold in the development of efficient catalytic systems for both industrial and academic research applications.
