摘要：

In this report we describe a very convenient synthetic method for the preparation in high yields and purity of cyclic [N3P3(OCH2CF3)(6)] and [N3P3(OC6H4R)(6)] (R = Pr CN, CHO, COC6H5, COCH3, H, OCH3), and polymeric [NP(OC6H4R)(2)](n) (R = Br, CHO, COC6H5, H, Bu-t) phosphazenes from the direct reaction of the trimer [N3P3Cl6] Or the high polymer [NPCl2](n), and the alcohol HO-CH2CF3 or the para-substituted phenols HO-C6H4R, using Cs2CO3 as proton abstractor and acetone or tetrahydrofuran as solvent.
