A series of chlorinated dimethyl tetrafluorodiazadiphosphetidines, [RF2PNMe]2, where R = ClCH2(I), Cl2HC (II), or Cl3C (III) have been studied. The syntheses of the two new members of this series, (II) and (III), are described. Analyses of the 31P-1H} and 19F-1H} noise-decoupled n.m.r. spectra yielded values for chemical shifts and coupling constants. In addition some 1H n.m.r. data are given, including

PNMe] 2,其中R = ClCH 2(I),Cl 2 HC(II)或Cl 3 C(III)。描述了该系列的两个新成员(II)和(III)的合成。通过对31 P- 1 H}和19 F- 1 H}噪声解耦的nmr光谱进行分析,得出了
化学位移和耦合常数的值。此外,给出了一些1 H nmr数据,包括计算机拟合(II)的结果。讨论了化合物的nmr参数和异构现象。
