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