A preparative method for the synthesis of first representatives of O,O-diphenyl N-sulfonylbenzimidoylphosphonates was proposed. The method involves oxidation of the corresponding α-(sulfonylamino)benzylphosphonates. The σ-constants of the N-sulfonylbenzimidoylphosphonate group were estimated by 19F NMR spectroscopy. The imidoylphosphonates obtained easily formed stable adducts at the C=N bond with
