    Abstract: A method for purifying a crude PNPNH compound of the general structure R1R2P—N(R3)—P(R4)—N(R5)—H wherein R1, R2, R3, R4 and R5 are independently halogen, amino, trimethylsilyl, C1-C10-alkyl, substituted C1-C10-alkyl, C6-C20-aryl and substituted C6-C20-aryl, or any cyclic derivative wherein at least one of the P or N atoms of the PNPN—H structure is a member of a ring system, the ring system being formed from one or more constituent compounds of the PNPNH-structure by substitution, the method comprising the steps: A. a) dissolving the crude PNPNH-compound in a C1-C10 alcohol or mixture thereof under heating; b) cooling the solution obtained in step a), c) precipitating the PNPNH compound, separating and optionally drying, or B. (i) washing the crude PNPNH compound with C1-C10 alcohol or a mixture thereof, (ii) separating the PNPNH compound and optionally drying thereof.

    Abstract translation: 纯化通式为R 1 R 2 P -N（R 3）-P（R 4）-N（R 5）-H）的粗PNPNH化合物的方法，其中R1，R2，R3，R4和R5独立地为卤素，氨基，三甲基甲硅烷基，C1- C 10 - 烷基，取代的C 1 -C 10 - 烷基，C 6 -C 20 - 芳基和取代的C 6 -C 20 - 芳基，或任何环状衍生物，其中PNPN-H结构的P或N原子中的至少一个是环的成员 该系统由一种或多种通过取代的PNPNH结构的组成化合物形成，所述方法包括以下步骤：a）a）将粗PNPNH化合物在加热下溶解在C1-C10醇或其混合物中; b）冷却步骤a）中获得的溶液，c）沉淀PNPNH化合物，分离并任选地干燥或B.（i）用C1-C10醇或其混合物洗涤粗PNPNH化合物，（ii）将PNPNH 化合物和任选地干燥。
