Abstract

A new phosphate substituted phosphazene trimer [N3P3Cl5(OP(O)Ph2)] has been synthesized and characterized by 31p NMR and Raman spectroscopy. The course of each solution-state substitution was followed with 31P NMR, and this technique was used to determine the best reaction conditions for the experiment. Information such as phosphorus to phosphorus connectivity and purity were analyzed. This paper will discuss the synthesis and characterization of phosphazene moieties which are substituted by phosphorus(V) centered substituents.
