Some new N-carbonyl, phosphoramidates with formula C6H5C(O)N(H)P(O)R2 (R NC3H6 (1), NC6H12 (2), NHCH2CHCH2 (3), N(C3H7)2 (4)) and CCl3C(O)N(H)P(O)R2 (R NC3H6 (5), NHCH2CHCH2 (6)) were synthesized and characterized by 1H, 13C, 31P NMR and IR spectroscopy and elemental analysis. The structures were determined for compounds 1 and 2. Compound 1 exists as two crystallographically independent molecules in crystal lattice. Both compounds 1 and 2 produced dimeric aggregates via intermolecular -PO...H-N- hydrogen bonds, which in compound 2 is a centrosymmetric dimer. In compounds with four-membered ring amine groups, 3J(P,C)>2J(P,C), in agreement with our previous studies about five-membered ring amine groups. Also, 3J(P,C) values in compounds 1 and 5 are greater than in compounds with five-, six- and seven-membered ring amine groups.
