The oxidation of phosphorus-(I) and -(III) oxyacids by benzyltrimethyl ammonium tribromide (BTMAB), in 9:1 (volume/volume) acetonitrile-acetic acid, leads to the formation of corresponding phosphorus-(III) and -(V) oxyacids. The reaction is first order with respect to each of the BTMAB and oxyacid. There is no effect of benzyltrimethylammonium chloride or bromide ion on the reaction rate. The oxidation of deuterated phosphinic and phosphorous acids exhibit the presence of a substantial kinetic isotope effect. The rate decreases with an increase in the proportion of acetic acid in the solvent. It has been shown that the reactive reducing species is the penta-coordinated form of the oxyacid. Tribromide ion has been postulated as the reactive oxidizing species. A mechanism involving a hydride-ion transfer in the rate-determining step has been proposed.
