A complete series of tetraphenyl-α,ω-alkanediyldiphosphine dioxides Ph2P(O)(CH2)nP(O)Ph2 (n = 1-10) was synthesized, and their extraction properties were studied. 1,5-Bis(diphenylphosphinoyl)pentane showed the highest extraction ability with respect to palladium. A synergistic effect was observed in the extraction of palladium with toluene solutions of 1,5-bis(diphenylphosphinoyl)pentane in the presence of tributyl phosphate.
