The Synthesis of New Phosphazene-Bearing Ethyl p-Hydroxybenzoate and Ferrocenyl Pendant Groups and their Spectroscopic and Crystallographic Characterizations

Herein, we report a study of novel hexachlorocyclotriphosphazene (N 3 P 3 Cl 6 ) derivatives bearing ethyl p-hydroxy benzoate and pendant ferrocenyl groups. Characterizations of the products [mono- 2, di- (geminal 3a; non-geminal trans a -3b, trans b -3c and cis -3d), tri- 4 and tetra- 5 substitue phosphazene derivatives] were performed using elemental analysis and spectral methods . The structure of the two compounds  (2 and 5) are elucidated by X-ray diffraction techniques.
