Recently, phosphoramide compounds have received considerable attention as a key factor for many biologically active molecules. They also show good performance as organic dyes, flame retardants and extractants. Therefore, developing an efficient and practical method to synthesize phosphoramides is of great importance [1]. Furthermore, Phosphoryl-based compounds, can be good representatives for complex reactions as well [2]. Consequently, in this work, the synthesis of two new phosphoramide compounds, P(O)(OC6H5)2(NHCSNHC7H13) (1) and P(O)(NHC6H11)2(NHCH(CH3)(C6H5)) (2) are reported. Characterization was performed by IR, NMR (1H, 13C, 31P) and Mass spectroscopies. Some carbon atoms with two and three bonds separations from phosphorus appear as doublets, due to the coupling with phosphorus. Typical values of coupling constants are 2J(P,C) = 6.1 Hz, 2J(P,C) = 5.3 Hz and 3J(P,C) = 4.5 Hz in (1) and 2J(P, C) = 3.0 Hz and 2J(P,C) = 6.1 Hz in (2).
