Other Methods of Preparing P-C Containing Compounds

There are other methods for preparing cyclophosphazenes containing P-C compounds. Condensation reactions involving the elimination MesSiX (X = Br, F) from N-(silyl)-P-(halogeno)phosphoranimines is a good method for the preparation of fully substituted alkyl- or arylcyclophosphazenes (see Eq. 3.19) [2, 14]. 

Friedel-Crafts reaction is quite useful to prepare gem-N3P3Cl4Ph2 and ge/ -N3P3Cl2Ph4 (see Eq. 3.21).
