A new, convenient synthesis of the linear phosphazene salt [Cl3P=N=PCl3]CI: Preparation of higher linear homologues [Cl3P=N-(PCl2=N)(x)=PCl3]CI (X=1-3) and the 16-membered macrocycle [NCCI(NPCl2)(3)](2)
An improved synthetic route to the linear phosphazene salt [CI3-P=N=PCI3]CI is reported. This species is a useful precursor to higher linear homologues and also to heterocycles such as the 16-membered carbophosphazene macrocycle [NCCI(NPCI2)(3)](2.)
