Small-Molecule Phosphazene-Substituted Phenoxy Side Groups Synthesis, X-RayStructures, and Comparisons with the Corresponding High Polymers

摘要

A series of new cyclic phosphazenes and a linear short chain phosphazene havebeen synthesized as models for the preparation of the corresponding high polymers. Several of the high polymers were also prepared. The small-molecule compounds were characterized by a combination of (31)P NMR, mass spectrometry, and elemental analysis. The crystal and molecular structures of hexakis(4-methylphenoxy) cyclotriphosphazene, hexakis(4-hydroxyphenoxy)
