Extraction of Sc(III) ions by new a-aminomethylphosphinoxides was studied. Preliminary experiments with acid solutions allowed for selection of low-basicity compounds, which demonstrated a poor coefficient of the acids ...

A series of bis- and tetra(phosphinoxymethyl)diamines was synthesized in a threecomponent Kabachnik-Fields reaction starting from a phosphinic acid, formaldehyde, and a diamine. The extracting properties of some selected ...
