Abstract: The synthesis of twelve novel 4-(0,0-dialkyl(diaryl)phosphoryl(thiophos- phoryl))hydrazono-2,3-dichloro-2-butenoic acids by the reaction of О,О-dialkyl(diaryl)phosphoryl(thiophosphoryl)hydrazines with 3-formy- 2,3- dichloro-2-propenoic acid is described. Infrared, ultraviolet, and ¹H NMR spectra of the prepared compounds forming intramolecular hydrogen bonds of the C = 0 • • • H - C =,O—H • • • CI, and N—H • • • CI types are interpreted.
