METHOD FOR PURIFYING A CRUDE PNPNH COMPOUND
The present invention relates to a method for purifying a crude PNPNH compound of the general structure R 1 R 2 P-N(R 3 )-P(R 4 )-N(R 5 )-H wherein R 1 , R 2 , R 3 , R 4 and R 5 are independently selected from halogen, amino, trimethylsilyl, C 1 -C 10 -alkyl, substituted C 1 -C 10 -a...

| description | The present invention relates to a method for purifying a crude PNPNH compound of the general structure
R 1 R 2 P-N(R 3 )-P(R 4 )-N(R 5 )-H
wherein R 1 , R 2 , R 3 , R 4 and R 5 are independently selected from halogen, amino, trimethylsilyl, C 1 -C 10 -alkyl, substituted C 1 -C 10 -alkyl, C 6 -C 20 -aryl and substituted C 6 -C 20 -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, comprising the steps: A. a) dissolving the crude PNPNH-compound in a C 1 -C 10 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 C 1 -C 10 alcohol or a mixture thereof, (ii) separating the PNPNH compound and optionally drying thereof. |
