synthesized two kinds of polyphosphine polyoxides. The first one has ether bridge, and the second one shows PCP linkage. Complexation properties of these compounds towards minor actinides (Np, Pu and Am) have been evaluated from liquid-liquid extraction and from transport by supported liquid membranes. In decorporation experiment, some of the synthesized phosphonates exhibit in vivo good uranyl or neptunium

Vinylic phosphorus compounds were found to react as Michael olefins with alcohols in basic catalytic conditions. Several phosphorylated polyethers were obtained in such a way. In analogous conditions, the hydroxymethylphosphine oxide used as alcoholic reagent looses formaldehyde leading to 1,2-diphosphorus compound formation.
