dichlorophosphino(dichlorophosphinyl)methylamine, Cl2P·NMe·P(O) Cl2 by dimethylaminotrimethylsilane and methoxytrimethylsilane respectively initially occurs at the tervalent phosphorus atom. The mono-dimethylamino-derivative Cl(Me2N)P·NMe·P(O)Cl2, rearranges to its isomer, Cl2P·NMe·P(O)ClNMe2 at ambient temperatures. Further dimethylaminolysis gives the bisdimethylaminoderivative, Cl2P·NMe·P(O)(NMe2)2 which
二氯膦基(二氯膦基)甲胺,Cl 2 P·NMe·P(O)Cl 2的二甲基氨基分解和甲氧基化最初分别在二价磷原子处被二甲基氨基三甲基硅烷和甲氧基三甲基硅烷发生。单甲基氨基-衍生物氯(ME 2 N)P·NME·P(O)氯2,重新排列到其异构体,氯2 P·NME·P(O)ClNMe 2在环境温度下。进一步的二甲基氨基分解得到双二甲基氨基衍生物Cl 2 P·NMe·P(O)(NMe 2)2,也可以通过其异构体Cl(Me 2 N)P·NMe·P(O)Cl(NMe 2)的重排形成)。单甲氧基衍生物Cl通过三氯化磷裂解甲氧基衍生物Cl(MeO)P(O)·NMe·SiMe 3中的硅氮键,得到2 P·NMe·P(O)Cl(OMe)。通过缩合反应制备双和三甲氧基衍生物Cl 2 P·NMe·P(O)(OMe) 2和Cl(MeO)P·NMe·P(O)(OMe) 2。二甲氧基(甲基氨基)氧化膦(MeO) 2(MeNH)PO,三氯化磷(
