Oligomeric Hydroxyaryloxyphosphase Based on Resorcinol

Abstract: By the reaction of hexachlorocyclosphosphazene with resorcinol in the immiscible pyridine–cyclohexane system, hexa-(m-hydroxyphenoxy)cyclotriphosphazene is synthesized, the optimum yield of which of 84% is achieved in a uniform mixture of the indicated solvents and the molar ratio HCP : resorcinol = 1 : 12. When used for the synthesis of oligomers mixtures of chlorocyclophosphazenes (PNCl2)n, where n = 3, 4, and 6, also complete replacement of chlorine atoms occurs, and with a yield of up to 80%, the formation of mixed oligohydroxyphenoxycyclophosphazenes takes place. The synthesized oligomers are characterized using 31P NMR spectroscopy and MALDI-TOF mass spectrometry. © 2019, Pleiades Publishing, Ltd.
