The behavior of phenyl hydrogen α-hydroxyiminobenzylphosphonate (E)-2 in aqueous hydrochloric acid solution was examined by 31P NMR spectroscopy and by HPLC. Compound (E)-2 was found to undergo two competing acid-catalyzed reactions. 1) Fragmentation to phenyl phosphate (6) and benzonitrile, similar to the fragmentation of other hydroxyiminophosphonates to metaphosphate examined previously. The fragmentation of ...
