1,2) with NN′-disubstituted aminotrimethylsilanes. R2N·SiMe3, provides a facile method of synthesis of fluorophosphoranes of types R2NPF4, (R2N)2PF3, RPF3NR′2, and R2PF2NR′2. When PF5 and RPF4 are allowed to react with N-substituted hexamethyldisilazanes, RN(SiMe3)2, the cyclic fluorophosphoranes, [RNPF3]2 and [R′NPF2R]2, are formed. Diphenyltri-fluorophosphorane with MeN(SiMe3)2 gives only a monomeric
五氟化磷和其有机衍生物,R的反应Ñ PF 5- Ñ(Ñ = 1,2)与NN '二取代aminotrimethylsilanes。[R 2 N·森3,提供的类型fluorophosphoranes的合成的简便方法R 2 NPF 4,(R 2 N)2 PF 3,RPF 3 NR' 2,和R 2 PF 2 NR' 2。当PF 5和RPF 4与N反应时形成取代的六甲基二硅氮烷,RN(SiMe 3)2,环状氟代膦酸酯,[RNPF 3 ] 2和[R'NPF 2 R] 2。具有MeN(SiMe 3)2的二苯基三氟磷烷仅产生单体氟膦酰亚胺MeNPFPh 2。作为五氟化磷的衍生物,报道的所有化合物均具有立体化学意义。介绍并讨论了它们的1 H,19 F和31 P nmr光谱。
