✦ Synopsis

Polyphosphane polyoxides with (O)PCP(O) linkages are allowed us to overcome a transmetallation reaction and thereby obtain polyphosphane polyoxides in good yields. powerful chelating agents for extraction of actinides from nuclear wastes. They are obtained either by the Michaelis-

The 1 H-NMR spectra of the PCH 2 P groups show the influence of the different R groups attached to the Arbuzov reaction of chloromethylphosphane oxides and phosphorus(III) esters, or by the reaction of phosphane oxide phosphorus atoms. We determined the coupling constants and the chemical shifts of these spin systems. carbanions with chlorophosphanes. With the latter method, the addition of a phosphane oxide carbanion in excess or sulfide [7] The major drawback of this procedure is a suc- [a] Ecole Nationale Supe ´rieure de Chimie de Montpellier, ESA, gives first phosphanylmethylphosphane oxides 6, (Scheme 5076 du CNRS 2), which are then oxidized, by hydrogen peroxide in di-
