A series of aminocyclodiphosph(III)azanes (R1R2N)[graphic ommitted]But(R1= H, alkyl, or SiMe3; R2= alkyl) have been prepared by the reactions of [graphic ommitted]But with primary or secondary amines, or with NMe(SiMe3)2. In some cases geometricalisomers have been separated by fractional crystallisation and thermal methods. Other cyclodiphosph(III)azanes, (Me2N) [graphic ommitted]R (R = Me or Et)
通过[图形省略] Bu的反应,制备了一系列氨基环二磷(III)氮杂烷(R 1 R 2 N)[图形省略的] Bu t(R 1 = H,烷基或SiMe 3; R 2 =烷基)。t与伯胺或仲胺,或与NMe(SiMe 3)2。在某些情况下,几何异构体已通过分步结晶和热方法分离。通过加热二膦胺(Me 2 N)2 P–NR–P(NMe )合成了其他环二磷(III)氮杂烷(Me 2 N)[图省略] R(R = Me或Et)。2) 2(R = Me或Et)在真空中。报告并讨论了这些衍生物的选定物理( 1 H, 13 C, 31 P nmr,ir,偶极矩和质谱)性质。
