Many small-molecule Si-N-P compounds of appropriate design can function as precursors to various oligomeric and polymeric P-N systems. For example, polydialkylphosphazenes, R2PNn, are readily obtained via the thermal condensation-polymerization of certain N-silylphosphinimines, Me3SiNPXR2. In addition, novel 3-coordinate phosphorus-V compounds including the bisimino-phosphoranes, RPNSiMe32, can potentially lead to new polymers of formula RPN sub n, the phosphorus analogs of electrically conducting SN sub n. The synthesis of polyphosphazenes and their precursors and the synthesis of potential precursors to RPN sub n are discussed.
