in ABSTRACT PhD Thesis THE SYNTHESIS AND CHARACTERIZATIONS OF CYCLOALCOHOL- SUBSTITUTED N-DICHLOROPHOSPHORYL-P- TRICHLOROMONOPHOSPHAZENE COMPOUNDS Ali İhsan ÖZTÜRK Fırat University Graduate School of Natural and Applied Sciencies, Department of Chemistry 2002, Page: 69 Phosphazenes, specially linear phosphazenes posses the biological activity. There are many studies about the synthesis, characterizations and applications of phosphazenes. In this study, the alcoholysis of N-dichlorophosphoryl-P-trichloromonophosp-hazene have been studied. Since linear phosphazenes are sensitive to air and moisture, experiments are carried out in Argon atmosphere. Cyclopentanol, cyclohexanol, 4-methylcyclohexanol, 3-methylcyclohexanol, 3- methylcyclopentanol and cyclopropanemethanol were chosen as substituents. The starting material, N-dichlorophosphoryl-P-trichloromonophosphazene, was prepared from phosphorus pentachloride and amonium sulphate. Their structure were defined by IR, elemental analysis, *H, 13C, 31P-NMR and mass spectroscopies. The defined coumpounds are N-di(cyclopentoxi)phosphoryl-P-tri(cyclopen- toxi)monophosphazene, N-(chloro, cyclohexoxy)phosphoryl-P-tri(cyclohexoxy)mono- phosphazene, N-di(4-methylcyclohexoxy)phosphoryl-P-tri(4-methylcyclohexoxy)mono- phosphazene,N-di(3-methylcyclohexoxy))phosphoryl-P-tri(3-methylcyclohexoxy)mono- phosphazene, N-di(3-methylcyclopentoxy)phosphoryl-P-tri(3-methylcyclopentoxy)mo- nophosphazenes. Phosphazene or any phosphorus compound could not be isolated from the reaction of phosphazene with cyclopropanemethanol.
