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

Abstract

A series of new cyclic phosphazenes and a linear short chain phosphazene have been 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)cyclotriphosphazene, hexakis(4-benzyl- oxyphenoxy)cyclotriphosphazene, octakis(4-phenoxyphenoxy)cyclotetraphosphazene, and (t-butylphenoxy)diphosphorus were investigated by single crystal X-ray diffraction techniques. jg p1
