Carbon‐13 chemical shifts and the POC, POCC, PNC and PNCC coupling constants of 18 compounds containing the amine moiety, and with the general formula Y 2 P(X)NHR [Y=C 2 H 5 O, C 6 H 5 O, CH 2 O, Y 2 =1,2‐dioxybenzene; X = O or S; R = H, CH 3 , C 2 H 5 , PhCH 2 CH 2 , (CH 3 ) 2 CH, C(CH 3 ) 3 , C 6 H 11 , C 6 H 5 , C 6 H 5 NH] have been determined. The Y 2 P(X) group shows a sterically induced effect on the amine moiety; the 13 C chemical shift of the Y group is, however, almost unaffected on replacing P(O) by a P(S) group.
