Abstract
The reaction of PSCl3 with Pr(i)2NH at 60 degrees C affords the disubstitution product (Pr(i)2N)2P(S)Cl without first forming the monosubstitution product Pr(i)2NP(S)Cl2; a P(III) compound (possibly PCl3) generated in situ seems to be a crucial intermediate.
摘要
在60℃下，PSCl₃与二异丙基胺反应生成二取代产物二异丙基氨基磷酰氯((Pr(i)₂N)₂P(S)Cl)，而不会先形成单取代产物二异丙基氨基磷二氯(Pr(i)₂NP(S)Cl₂)；原位生成的一种P(III)化合物（可能是PCl₃）似乎是关键中间体。
