investigated. When R = Me, mono-, non-geminal bis-, and tetrakis-dimethylamino-derivatives have been isolated, and the new ring compound (II), Me2N(S)[graphic omitted], obtained by reaction with 6 mol dimethylamine heated under reflux in chloroform solution. The analogous N-ethyl ring compound has been obtained from (I; R = Et). Attempts to synthesise the geminal bis(dimethylamino) derivatives, Cl2(S) P·NR·P(S)(NMe2)2
研究了[Cl 2(S)P] 2 NR(I; R = Me或Ph)与二甲胺的反应。当R = Me时,已分离出单,非二元双和四甲基二甲基氨基衍生物,并通过与6 mol反应获得新的环化合物(II)Me 2 N(S)[未显示图形]。二甲胺在氯仿溶液中加热回流。从(I; R = Et)获得了类似的N-乙基环化合物。尽管Cl 2(S)P·NHPh与二甲胺反应生成(2)的双双(二甲基氨基)衍生物双(二甲基氨基)衍生物Cl 2(S)P·NR·P(S)(NMe 2)2的尝试仍未成功。我2 N)2(S)P·NPh·P(S)(NMe 2)(NHPh)。二甲胺,(二甲基氨基)三甲基硅烷和(二乙基氨基)三甲基硅烷对Cl 2(O)P·NMe·P(S)Cl 2的氨基解离首先在非给体溶剂中的膦硫代酰基中心发生,但在乙醚溶液中优先发生二甲基氨基解离在膦酰基中心。对于Cl 2(O)P·NPh·P(S)Cl 2也获得了相似的结
