Abstract

An improved synthesis of the phosphazene polymerization precursors, hexachlorocyclotriphosphazene, (NPCl₂)₃ (1), and Cl₃P=NSiMe₃ (2) is reported. The addition of PCl₅ to N(SiMe₃)₃ in methylene chloride at 40 °C produced a mixture of phosphazenes which contained 76% of 1. However, the addition of N(SiMe₃)₃ to PCl₅ in methylene chloride at 0 °C, followed by the addition of hexane, provided 2 in 40% yield. The mechanism of the reaction is discussed.
