PHOSPHINYLMETHYLPHOSPHINATES AS CHELATING LIGANDS.
Abstract
(Dimethylphosphinyl)-,(methylphenylphosphinyl)-, and (diphenylphosphinyl)-methylphenylphosphinic acids were prepared by hydrolysis of the Michaelis-Arbuzov reaction products of the appropriate chloromethyl-phosphine 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 'H NMR spectra are discussed. (Author)
