文摘

A new binucleating tetraphosphine ligand, rac- and meso-(Et₂P-1,2-C₆H₄)P(Ph)CH₂(Ph)P(1,2-C₆H₄PEt₂) (et,ph-P4-Ph), has been synthesized. Separation and purification of the ligand diastereomers have been accomplished via column chromatography. Ni₂Cl₄(et,ph-P4-Ph) complexes of both diastereomers have been prepared in high yield and crystallographically characterized.
