Synthesis and Structure of Small-Molecule Cyclic Phosphazenes Bearing Ortho-Substituted Aryloxy and Phenoxy Substituents

摘要

A series of cyclic, trimeric, and tetrameric phosphazenes with ortho-substitutedaryloxy side groups have been synthesized. The ortho-substituents are methyl and phenyl groups. These compounds are structural models for the corresponding high polymeric phosphazenes.
