Abstract:

The chemistry of P-N compounds is characterized by the existence of polymeric compounds. Many derivatives of the six membered ring system NPClsub2 and of the eight membered system NPClsub 2sub 4 are known Therefore, the reaction of PClsub 5 with NHsub 4Cl has been studied The intermediates of this reaction could be isolated. In the re port a short review of useful substances derived from the trimeric and the polymeric phospho-nitrilic chlorides is given. There are also four membered P-N ring compounds. These four membered ring systems their preparation and their properties e.g. their structure, are described. Polymeric substances containing such a four membered ring system are formed with aromatic dihydroxy compounds and also with CrCOsub 6. Some four membered ring systems may be condensated. A compound with 3 four membered P-N ring systems was formed, in which the 3 ring systems are connected by a P-Cl bridge. There are also such ring systems in which 1 or more phosphorus atoms are substituted by S02 groups. Special attempts have been made to synthesize thermostable and flame resistant materials on the basis of P-N-C compounds. Therefore the reaction of guanidine and PClsub 5 was studied Other compounds were prepared by the reaction of PClsub 5 with cyanamide and with dicyandiamide, e.g. phosphatriazines could be prepared. New hetero cycles with four and five membered P-N ring systems were obtained by the reaction of oxamide and PCl Such ring systems can be connected with each other. Finally a very promissing product was obtained by the reaction of PCl and Liquid ammonia.
