摘要
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.
