PROBLEM TO BE SOLVED: To provide a method for producing a cyclic aryloxyphosphazene in a short time and in high yield under a mild condition by a simple operation. SOLUTION: Provided is a method for producing a cyclic aryloxyphosphazene represented by Formula (2), comprising reacting hexachlorocyclotriphosphazene with an aryl alcohol in a nitrile only or an organic solvent mixed with 40 vol.% or more and less than 100 vol.% of a nitrile in the presence of a pellet-like material of al least one hydroxide selected from the group consisting of potassium hydroxide and sodium hydroxide. [Ar is a substituted or unsubstituted aryl group.] SELECTED DRAWING: None COPYRIGHT: (C)2020,JPO&INPIT

Hexaaryloxyphosphazenes [N3P3(O-C6H4-R)6] (R=H, CH3, OCH3, C(CH3)3, CHO, COCH3, COOR, C6H5, NO2, F, etc) were readily obtained with ca 70% isolated yield in refluxing acetonitrile in the presence of anhydrous potassium phosphate. All compounds were characterized by means of elemental analysis, 1H-NMR, 31P-NMR spectroscopy.
