The synthesis of new phosphazene-bearing ethyl p-hydroxybenzoate and ferrocenyl pendant groups and their spectroscopic and crystallographic characterizations

This is a study of new hexachlorocyclotriphosphazene (N₃P₃Cl₆) derivatives bearing ethyl p-hydroxybenzoate and ferrocenyl pendant 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 substituted phosphazene derivatives] were performed using elemental analysis and spectral methods. The structures of the two compounds (2 and 5) were explained by the use of X-ray diffraction techniques.
