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.
