Treatment of Pri2P(O)Cl with Me3SiNHOSiMe3 gives Pri2P(O)NHOSiMe3, which is desilylated by methanol giving Pri2P(O)NHOH. The O-p-nitrobenzenesulphonyl derivative of this rearranges with KOBut in ButOH, an isopropyl group migrating from P to N and the phosphonamidate PriP(O)(OBut)NHPri being formed quantitatively. Rearrangement also occurs in other alcohols (MeOH, EtOH, PriOH), but not quite as cleanly
用Me 3 SiNHOSiMe 3处理Pr i 2 P(O)Cl产生Pr i 2 P(O)NHOSiMe 3,其被甲醇甲硅烷基化,得到Pr i 2 P(O)NHOH。所述ø - p此重排用的甲部衍生物-nitrobenzenesulphonyl吨在卜吨OH,异丙基迁移从P到N和镨的磷酰胺酯我P(O)(OBU吨)NHPr我被定量地形成。重排也发生在其他的醇(甲醇,乙醇,镨我OH),但不是很干净。在卜Ť NH2所述phosphinoylhydrazine镨我2 P(O)NHNHBu吨形成以及重排产物,镨我P(O)(NHBu吨)NHPr我。与Me 3 SiNHOSiMe 3相似地制备的Et 2 P(O)NHOH和Pr i MeP(O)NHOH的对硝基苯磺酰基衍生物也与Bu t OH-KOBu t进行了定量重排。在后一种情况下,两个烷基(Pr i和Me)的迁移能力几乎相同。

On photolysis in methanol di-t-butylphosphinic azide (4; R = But) rearranges with loss of nitrogen to give methyl NP-di-t-butylphosphonamidate (6; R = But, X = OMe)(71%), presumably by way of a monomericmetaphosphonimidate (5; R = But) which is trapped by the solvent. Analogous rearrangements occur in other alcohols and in t-butylamine, although di-t-butylphosphinic amide is also a substantial product
在甲醇中进行光解时,二叔丁基次膦叠氮化物(4; R = Bu t)在失去氮的情况下重排,得到NP NP-二叔丁基膦酰胺酸甲酯(6; R = Bu t,X = OMe)(71%),大概是通过被溶剂捕获的单体偏亚膦酸酯(5; R = Bu t)。尽管二叔丁基次膦酰胺在乙醇中也是主要产物,而在异丙醇中是主要产物,但在其他醇和叔丁胺中也会发生类似的重排。二isopropylphosphinic叠氮化物(4; R = PR我)以类似的方式的行为,但在甲醇中较少受阻二乙基次膦叠氮化物(4; R = ET)患有广泛溶剂分解,以二乙基次膦酸甲酯。
