Bis(2-diphenylphosphino)ethyl ether（Cat No.:L002885）is a bidentate diphosphine ligand featuring two diphenylphosphino groups connected via a flexible ethylene ether backbone. This compound is commonly used in coordination chemistry and homogeneous catalysis, particularly in transition metal-catalyzed reactions such as hydrogenation, hydroformylation, and cross-coupling. The ether linkage provides flexibility, allowing the ligand to adopt various coordination geometries, which can fine-tune the reactivity and selectivity of metal centers. Its strong σ-donating phosphine groups enhance metal–ligand stability, making it valuable in designing efficient and robust catalytic systems for organic synthesis and industrial processes.
