Synthesis and spectroscopic characterization of cyclic and polymeric phosphazenes bearing phosphine complexes
摘要:
The reactions of the cyclic phosphazenes [N3P3Cl6] and [N3P3(O2Cl2H8)(2)Cl-2] (O2Cl2H8 = 2,2'-dioxybiphenyl) with the diphenylphosphine phenol complex {Mn(CO)(2)(eta(5)-C5H4Me)[PPh2(C6H4-OH)]} (1) and Cs2CO3 in refluxing acetone gave, respectively the phosphazenc-phosphine complexes {N3P3[OC6H4PPh2-Mn(CO)(2)(eta(5)-C5H4Me)](6)} (2) and {N3P3(o(2)Cl(2)H(8))(2)[OC6H4PPh2-Mn(CO)(2)(eta(5)-C5H4Me)](2)} (3). in good yields. The analogous reaction of the partially substituted clorophosphazene polymer {[NP(O2Cl2H8)](0.6)[NPCl2](0.4)}(n) in THF gave the polymeric complex [{NP(O2Cl2H8)}(0.6){NP[OC6H4PPh2-Mn(CO)(2)(eta(5)- C5H4Me)](2)}(0.4)-0.5[OC4H8](n) (4). Different spectroscopic data are provided for the new compounds that may be useful for the characterization of other more complex polymeric materials. (C) 2002 Elsevier Science Ltd.
