New water-soluble selenium-containing nano-biocomposites have been synthesized by oxidation of sodium bis(2-phenylethyl)phosphinodiselenoate with hydrogen peroxide using humic substances to stabilize selenium nanoparticles. As shown by a set of physicochemical methods, the obtained hybrid nanocomposites are formed as spherical hexagonal selenium particles with a size of 13-30 nm, dispersed in a humic matrix.

Secondary phosphine selenides, R(2)P(Se) H (R = PhCH(2)CH(2), PhCH(Me) CH(2), 4-t-BuC(6)H(4)CH(2)CH(2), NaphthylCH(2)CH(2), Ph), react with the system Se/MOH (M = Li, Na, K, Rb, Cs) in the system THF/EtOH at ambient temperature unusually fast (20-30 s) to give cleanly and almost quantitatively (in 94-100% yield) earlier unknown diorganodiselenophosphinates of alkali metals.

Redox reaction between alkali metal diselenophosphinates R2P(Se)SeM (M = Na, K) and elemental iodine in a 2:1 molar ratio (1,4-dioxane, room temperature, 2 min) gives bis(diorganylselenophosphoryl)selenides [R2P(Se)](2)Se and bis(diorganylselenophosphoryl)triselenides [R2P(Se)](2)Se-3 in 87-90% total yields.
