Using phosphorus pentachloride as a substrate, carbacylamidophosphates of the general formula (R)C(O)NHP(O)(NC4H8O)2, where R = CH2Cl I; CHCl2 II; CCl3 III; CF3 IV; p-Me-C6H4V; p-Br-C6H4 VI; p-Cl-C6H4 VII, were prepared and characterized by 1H, 31P and 13C NMR, IR spectroscopy and elemental analysis. Different carboxylic amides attached to phosphorus nuclei affect on IR and NMR spectra. Three-bond coupling constants between phosphorus and carbon nucleus, 3J(P,Caliphatic) in the synthesized compounds, were greater than two-bond coupling constants, 2J(P,Caliphatic). The structures of IV and VI were determined by single-crystal X-ray diffraction techniques. The compounds IV and VI formed centrosymmetric dimers via intermolecular N-HźźźO=P hydrogen bonds.
