SYNOPSISA very convenient synthetic method is described for the known cyclic aryloxyphosphazenes [N3P3(OC6H4-R)6] (R = Br, CN, CHO, COCH3, COC6H5, and NO,). The method is based on the direct reaction of [N3P3C16] with six equivalents of the para-substituted phenols HOC6H4-R and K&03 in refluxing acetone and is characterized by very short reaction times and very simple workups, leading directly to the analytically and spectroscopically pure products in very high yields. In the cases where R = H, But, or OCH3, the reactions were much slower, but the time could be shortened by using [Bu4N]Br as the phase-transfer catalyst. Similarly, the polymers [NP(OC6H4-R),], can be conveniently obtained in ca. 70% and good analytical purity from polydichlorophosphazene [NPCl,], and the parasubstituted phenols HOC6H4-R (R = Br, CN, COCH3, COC6H5, and NO2) in the presence of K2C03 using THF as the solvent.
