Raman Scattering Study of Sodium Di-n-pentyl Phosphate Aggregates and Water Content Dependence of Conformation about P-O Bonds in Coagel Phases

For anhydrous sodium di-n-pentyl phosphate (DPP) in the solid state and the DPP-H2O system, the Raman scattering spectra due to the according vibration mode were investigated in the temperature range -80-100 deg C.For anhydrous DPP, the GG form about the P-O bonds was stabilized at lower temperatures.In the coagel phases of DPP-H2O, preferential stabilization of a specific rotational isomer about the P-O bonds occurred and the species of stabilized conformer was dependent on the water content; for the 7:3 DPP-H2O coagel the TT form was stabilized, while for the 8:2 DPP-H2O coagel the GT form was preferentially stabilized.The stabilization of such a specific conformer was also reflected in some conformationally sensitive Raman bands in the higher frequency region.

Synthesis of dialkyl phosphites and trialkyl phosphates by oxidation of sodium hypophosphite by copper(II) chloride

Sodium hypophosphite oxidazies in alcoholic solution of CuCl2 at 50-80 deg C to give dialkyl phosphite and trialkyl phosphate.The yield of trialkyl phosphate increases with decreasing molecular weight of the alcohol and reaches ca. 100percent for MeOH and EtOH.The optimal conditions were found, and the mechanism of oxidation of NaPH2O2 to (RO)2PHO and (RO)3PO by copper(II) chloride was studied.The reaction proceeds via the formation of alkyl hypophosphite and copper(II) complexes with alkyl hypophosphite and dialkyl phosphite, which undergo inner-sphere two-electron redox decomposition with the liberation of dialkyl phosphite and trialkyl phosphate, respectively.
