Synthesis and Characterization of Cyclotriphosphazenes Bearing Chalcones Derivatives

A series of new cyclotriphosphazenes bearing chalcones derivatives, N₃P₃Cl₅OC₆H₄ CH=CHC(O)C₆H₄OC_nH_2n+1] and N₃P₃OC₆H₄CH=CHC(O)—C₆H₄OC_nH_2n+1]₆, has been synthesized. A convenient synthetic method was performed from the reaction of hexachlorocyclotriphosphazenes with one and six equivalents of (E)-3-(4-(alkyloxy)phenyl)-1-(4-hydroxyphenyl)prop-2-en-1-one (2a–c). The compounds differ in the length of alkyl groups, C_nH_2n+1, where n = 10, 12, and 14, respectively. All the products were obtained in high yields. The structures of the synthesized compounds were defined by elemental analysis, IR, ¹H, ¹³C, and ³¹P NMR.
