amines, [Cl2P(S)]2NR and Cl2PS·NR·PCl2(R = Me, Et, or Ph), have been prepared by reactions of the bis(dichlorophosphino)-amines, (Cl2P)2NR (R = Me, Et, or Ph), with elemental sulphur in the presence of anhydrous aluminium chloride. The compounds Cl2P(S)·NR·PCl2 eliminate PCl3 when heated leaving cyclodiphosphazanes, [R·NP(S)Cl]2. Dichlorophosphinothioyl(dichlorophosphinyl)amines, Cl2P(S)·NR·P(O)Cl2(R
胺的二氯膦硫基酰基衍生物[Cl 2 P(S)] 2 NR和Cl 2 PS·NR·PCl 2(R = Me,Et或Ph)是通过双(二氯膦基)-胺的反应制备的, (Cl 2 P)2 NR(R = Me,Et或Ph),在无水氯化铝存在下具有元素硫。化合物Cl 2 P(S)·NR·PCl 2加热时消除PCl 3,剩下环二磷氮烷[R·NP(S)Cl] 2。二氯膦硫基(二氯膦基)胺,Cl 2 P(S)·NR·P(O)Cl 2(R = Me,Ph)和双(二氯膦硫基)胺,[Cl 2 P(S)]在三乙胺存在下,通过将Cl 2 P(S)·NHR与P(O)Cl 3或P(S)Cl 3分别缩合,制得2 NR(R = Me,Ph)。在大气压力下,以上所有化合物对无水氯化氢均无反应。讨论了这些化合物的1 H和31 P nmr和ir光谱。
