Phosphinylmethylphosphinates as chelating ligands
King,Block,Popoff
, p. 198 - 202 (1965)
(Dimethylphosphinyl)-, (methylphenylphosphinyl)-, and (diphenylphosphinyl)methylphenylphosphinic acids have been prepared by hydrolysis of the Michaelis-Arbuzov reaction products of the appropriate chloromethylphosphine oxides and diethyl phenylphosphonite. They react with Zn(C2H3O2)2·2H2O and Cr(C5H7O2)3 under suitable conditions to yield the corresponding bis and tris chelates, except for the diphenyl-chromium(III) derivative, which was prepared in low yield via the chromium(II) derivative. The zinc derivatives are dimers, the chromium derivatives monomers. The metal chelates are more thermally stable than the corresponding acetylacetonates. Their infrared and 1H n.m.r. spectra are discussed.

The reactivity of diarylphosphine oxides RR'P(O)CH2X with p-O2NC6H4ONa in DMF have been studied.The reaction rate increases with the electrodrawing properties of the substituents on R and R' in the following way: p-Me2NC6H4 2 reaction rate of diphenylphosphine oxides has been investigated.The reactivity increases as follows Cl I Br OTs.A reaction mechanism is suggested.
