Solvent-free microwave synthesis of trialkylphosphates

Trialkylphosphates are synthesized from alcohols by reaction with reactive phosphorus oxychloride under microwave irradiations and classical heating. Effects of these irradiations on the nature of the products and on the yield are studied. The compounds were characterized by their spectroscopic data and elemental analysis. The obtained results show that the products of these reactions are essentially trialkylphosphates and alkylphosphoric acids. They always show as the nature of the formed products and the yields in trialkylphosphates are comparable to those obtained in the classical conditions of heating. The speed of the reaction was increased by a factor from 40 to 120.

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.
