| Abstract: | Abstract A series of novel side group-modified cyclotriphosphazene derivatives were synthesized by the reaction of hexachlorocyclotriphosphazene N3P3Cl6] with 2,2′-diphenol and the potassium salt of 4-hydroxybenzaldehyde, and subsequent reduction of aldehyde groups to alcohol groups by the use of sodium borohydride. The bromination reaction was carried out with PBr3 to give N3P3(O2C12H8) (p-BrCH2-C6H4-O-)4. This compound was employed in reactions with macrocyclic polyamides, imidazole, or morpholine to produce title compounds. The target compounds were characterized by 1H NMR, 31P NMR, 13C NMR, and electrospray ionization mass spectrometry. Supplemental materials are available for this article.
