Synthesis and spectroscopic characterization of two new phosphoramides

Recently, phosphoramide compounds have received considerable attention as a key factorfor many biologically active molecules. They also show good performance as organic dyes,flame retardants and extractants. Therefore, developing an efficient and practical method tosynthesize phosphoramides is of great importance [۱]. Furthermore, Phosphoryl-basedcompounds, can be good representatives for complex reactions as well [۲]. Consequently, in thiswork, the synthesis of two new phosphoramide compounds, P(O)(OC۶H۵)۲(NHCSNHC۷H۱۳) (۱)and P(O)(NHC۶H۱۱)۲(NHCH(CH۳)(C۶H۵)) (۲) are reported. Characterization was performed byIR, NMR (۱H, ۱۳C, ۳۱P) and Mass spectroscopies. Some carbon atoms with two and three bondsseparations from phosphorus appear as doublets, due to the coupling with phosphorus. Typicalvalues of coupling constants are ۲J(P,C) = ۶.۱ Hz, ۲J(P,C) = ۵.۳ Hz and ۳J(P,C) = ۴.۵ Hz in (۱)and ۲J(P, C) = ۳.۰ Hz and ۲J(P,C) = ۶.۱ Hz in (۲).
