An azide and transition metal-free method for the synthesis of elusive phosphonic, phosphinic, and phosphoric monoacids has been developed. Inert pentavalent P(v)-compounds (phosphonate, phosphinate, and phosphate) are activated by triflate anhydride (Tf2O)/pyridine system to form a highly reactive phosphoryl pyridinium intermediate that undergoes nucleophilic substitution with H2O to selectively deprotect one alkoxy group and form organophosphorus monoacids.

It was found that mixed diesters of phosphoric acid and pyrophosphates were obtained in good yields when alcohols and arylphosphates, respectively, were allowed to react with 4-methoxyphenyl N-(2-aminophenyl) phosphoramidate in the presence of cupric chlo
