摘要：

The reactions of the cyclotriphosphazenes [N3P3Cl6] or [N3P3(O2C12H8)(2)Cl-2] with the phenolic phosphine PPh2(C6H4-OH) in the presence of Cs2CO3 give, respectively, the cyclic phosphazene phosphines [N3P3(OC6H4PPh2)(6)] (1) and [N3P3(O2C12H8)(2)(OC6H4PPh2)(2)] (2), very pure and in high yield. The similar reaction with the linear polyphosphazene {[NP(O2C12H8)](0.65) [NPCl2](0.35)}(n) in THF gives the diphenylphosphine polymer {[NP(O2C12H8)](0.65)[NP(OC6H4PPh2)(2)]0.35}(n) (3). The phenolic tungsten pentacarbonyl complex {W(CO)(5)[PPh2(C6H4-OH)]} reacts in the same way with those cyclic and polymeric phosphazenes to give the corresponding complexes {N3P3[OC6H4PPh2-W(CO)(5)](6)} (4), [N3P3(O2C12H8)(2)(OC6H4PPh2-W(CO)(5))(2)] (5), and {[NP(O2C12H8)](0.65)[NP(OC6H4PPh2-W(CO)(5))(2)](0.35)}(n) (6).
