Polyphosphazene-bound Wittig reagents such as $[NP(OC_6H_5)_{1.7}(OC_6H_4P(Ph)_2$=$CHCH_2CH_2CH_3)_{0.3}]_n$ were synthesized by treating $[NP(OC_6H_5)_{1.7}(OC_6H_4Br)_{0.3}]_n$ with n-butyllithium, diphenylchlorophosphine, and n-butyl iodide. Polymeric reactions were carried out according to the reaction conditions with cyclic primers such as [$N_3P_3(OC_6H_5)_5(OC_6H_4P(Ph)_2$)]. The desired alkene and polymer-bound phosphine oxide were prepared successfully by the reaction of polyphosphazene-bound Wittig reagents with benzophenone.
