A procedure for preparing N-sulfonyl- and N-phosphorylbenzimidoylphosphonates by oxidation of the corresponding alpha-(sulfonylamino)- and alpha-(phosphorylamino)benzylphosphonates was developed. The sigma constants of imidoylphosphonate groups were evaluated by F-19 NMR spectroscopy, and specific features of their electronic effects were considered. The reactions of the imidoylphosphonates obtained with O-, S-, P-, and N-nucleophiles were studied. The phosphonate-phosphoramidate rearrangement of alpha-aminobenzylidene-bisphosphonates was found.
