Selective mono substitution of cyclotri-phosphazene by 2-Hydroxyethylacrylate producing new acrylate cyclo-triphosphazene

Abstract

In this work, new acrylate cyclotriphosphazene moiety (PN-A) was successfully synthesized starting from cyclotriphosphazene (PN) compound. This compound reacted with 2-hydroxyethylacrylate utilizing 1:1 mole ratio to increase the priority of one substitution reaction and forming PN-A molecule. The crud product was purified by recrystallization using n-hexane and column chromatography using cyclohexane: ethyl acetate 60:40 mL ratio as eluent. The obtained pure target product was characterized using FTIR, 1H NMR, 13C NMR, and 31P NMR techniques. All spectra demonstrates the chemical structure of the product hence the showed all required peaks to identify it.
