Bis(2-(bis(diethylamino)phosphino)phenyl) ether
Bis(2-(bis(diethylamino)phosphino)phenyl) ether (CAS 391208-78-9; C28H48N4OP2; molar mass 518.65 g/mol) is an air- and moisture-sensitive bidentate aminophosphine in which two diethylamino-substituted phosphino groups are held on a diphenyl ether backbone. This polydentate phosphorus ligand is used in coordination chemistry and homogeneous catalysis as a precursor and chelating donor for transition-metal complexes. Tech Serve Solutions supplies it at 95% assay for research and synthesis.

Phosphine ligand for homogeneous catalysis
Serves as a bidentate, ether-bridged phosphorus ligand for preparing transition-metal complexes. Its chelating geometry supports the design of catalysts for coordination and organometallic studies.
Aminophosphine building block
The P–N (diethylamino) bonds provide reactive sites for converting the phosphorus centres into other phosphine, phosphonite or phosphoramidite derivatives. This makes it a versatile intermediate in ligand synthesis.
Coordination and inorganic chemistry research
Used to study chelation, metal–ligand bonding and complex stability with a rigid diphenyl ether spacer. Suited to academic and industrial coordination-chemistry programmes.
Chemical synthesis reagent
Applied as a specialist reagent in laboratory-scale synthesis where a polydentate phosphine donor is required. Handling is carried out under inert, anhydrous conditions.
