Abstract

Abstract Polyphosphane polyoxides with (O) PCP (O) linkages are powerful chelating agents for extraction of actinides from nuclear wastes. They are obtained either by the Michaelis–Arbuzov reaction of chloromethylphosphane oxides and phosphorus (III) esters, or by the reaction of phosphane oxide carbanions with chlorophosphanes. With the latter method, the addition of a phosphane oxide carbanion in excess allowed us to overcome a ...
