Notes:
Under suitable conditions, PCL5 reacts and quantitatively with NH4Cl to form [Cl3P = N-PCl3] [PCl6], which, with additional PCl5 and NH4Cl, is transformed to [Cl3P = N-PCl2 = N-PCl3] [PCl6].The cation of the latter compound and the NH4+ ion react with ring closure to form [NPCl2]3, together with longer chains which can yield with NH4+ either [NPCl2]4 or, for example, Cl3P = N-(PCl2 = N) n-PCl2 = NH. The salt-like intermediates of the phosphonitrilic chloride synthesis react with S02 to form the oxygen-containing products, Cl3P = N-P(O)Cl2 and Cl3P = N-PCl2 = N-P(O)Cl2. Sulfur analogs are also easily obtained. The constitution of the compounds was determined by nuclear magnetic reasonance spectroscopy.
