A convenient method of synthesis of phosphoryl-substituted podands with dipehnylphosphorylmethyl end groups of the general formula Ph2P(O)CH2O(CH2CH2O)nCH2P(O)Ph2 (Ln, n = 0–6) is described. The stability constants of the complexes of the podands with alkali metal 2,4-dinitrophenolates were determined by conductometry. The ion-selective properties of the podands with respect to alkali and alkaline-earth metal cations were assessed by ionometry. The crystal structure of 1,3-bis(diphenylphosphoryl)-2-oxapropane was established by X-ray diffraction analysis.

An improved procedure for preparing bis(diphenylphosphinoylmethyl) ethers of oligoethelene glycols of the general formula Ph2P(O)CH2O(CH2CH2O)nCH 2P(O)Ph2 (n = 0-6) is developed, and the stability constants of their alkali cation complexes in the THF-CHCl3 system at 25°C were determined by conductometry.

It was shown that phosphonates and tertiary phosphine oxides can be synthesized by the alkylation of acid phosphites and diarylphosphine oxides in a nonpolar solvent in presence of solid potassium hydroxide and potassium carbonate and also catalytic amounts of 18-crown ether (or in its absence). (Diarylphosphinyl)methyl ethers of mono- and oligo-etylene glycols were synthesized by the reactions of diaryl(chloromethyl)phosphine oxides with lithium glycolates
