Article abstract of DOI:10.1134/S1070363206080068

A procedure for preparing N-sulfonyl-and N- phosphorylbenzimidoylphosphonates by oxidation of the corresponding α-(sulfonylamino)-and α-(phosphorylamino)benzylphosphonates was developed. The σ constants of imidoylphosphonate groups were evaluated by ¹⁹F 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 α-aminobenzylidene-bisphosphonates was found.
