[NP(OC_6H_5)_(1.7)(OC_6H₄P(Ph)₂=CHCH₂CH₂CH₃)_(0.3)]_n과 같은 포스파젠 고분자에 부착된 Wittlg 시약을 [NP(OC_6H_5)_(1.7)(OC_6H₄Br)_(0.3)]_n에 n-butyllithium, diphenylchlorophosphine, 그리고 n-butyl iodide 등으로 처리하여 만들었다. 고분자의 반응들은 [NP(OC_6H_5)_5(OC_6H₄P(Ph)₂)]와 같은 고리형 삼중체를 이용한 모델반응 조건들을 고려해 이루어졌다. 포스파젠 고분자에 부착된 Wittig 시약과 benzophenone을 반응시켜 원하는 알켄과 고분자에 부착된 phosphine oxide를 성공적으로 만들었다.

Polyphosphazene-bound Wittig reagents such as [NP(OC_6H_5)_(1.7)(OC_6H₄P(Ph)₂=CHCH₂CH₂CH₃)_(0.3)]_n were synthesized by treating [NP(OC_6H_5)_(1.7)(OC_6H₄Br)_(0.3)]_n with n-butyllithium, diphenylchlorophosphine, and n-butyl iodide. Polymeric reactions were carried out according to the reaction conditions with cyclic trimers such as [N₃P₃(OC_6H_5)_5(OC_6H₄P(Ph)₂)]. The desired alkene and polymer-bound phosphine oxide were prepared successfully by the reaction of polyphosphazene-bound Wittig reagents with benzophenone.
