Synthesis and Membrane Transport Properties of N-Functionalized α-Aminophosphine Oxides

Abstract

New lipophilic mono- and bisphosphinylamines including those possessing additional potential centers of coordination were synthesized on the basis of the Kabachnik–Fields reaction, and membrane transport properties of the synthesized compounds toward the rare and rare-earths were studied. Highly effective extractant of Sc(III) was found possessing a high degree of selectivity in the separation of Sc(III) ions from the ions of satellite metals.

Keywords:
