Notes:
The 1H and 31P NMR spectra of a series of compounds containing the PIII-N-PV skeleton including Cl2PNMeP(Z)Cl2 (Z=O or S), Cl2P·NMe·P(O)CINMe2, P4(NMe)6Zn (Z=S, n = 1-3; Z=Se, n = 1), XP(NBut)2P(Z)X (X=Cl, Z=O or S; X=OMe, Z=S or Se; X=NMe2, Z=S or Se; X=NEt2, Z=Se), (X=O or S), and Ph2PNRP(S)Ph2 (R=Me, Et) have been obtained. 1H-{31P} double resonance, and in selected cases, 31P-{1H, 77Se} and 31P-{1H, 31P} triple resonance experiments, indicate that 2J(PIII NPV) is positive in acyclic compounds, negative in most cyclic or cage compounds, and furthermore, is related to the conformation adopted by the PIII-N bond.
