Dialkyl hydrogen phosphates, RO(R′O)PO2H, are produced frommonoalkyl hydrogen phosphonates, RO(HO)PHO, by oxidation either with bromine in pyridine or with carbon tetrachloride and triethylamine with stoicheiometric quantities of an alcohol. In the absence of an alcohol, the former reagent gives sym-dialkyl dihydrogen pyrophosphates in good yield. The nature of the phosphorylating entity in each system
