在富电子烯烃存在下,二烷基磷或氯化砷 [(Me3Si)2CH]2MCl (M = P 或 As) 或双酰氨基磷或氯化砷 [(Me3Si)2N]2MCl (M = P 或 As) 的甲苯溶液光解,产生含有持久性(t½ > 1 个月,在 20 °C 下)双配位磷或砷中心的溶液自由基[(Me3Si)2CH]2M·或[(Me3Si)2N]2M·(M = P或As)的特征在于它们的e.s.r。光谱。
Photolysis of toluene solutions of dialkyl-phosphorus or -arsenic chlorides [(Me3Si)2CH]2MCl (M = P or As) or bisamido-phosphorus or -arsenic chlorides [(Me3Si)2N]2MCl (M = P or As) in the presence of an electron-rich olefin leads to solutions containing persistent (t½ > 1 month at 20 °C) two-co-ordinate phosphorus or arsenic-centred radicals [(Me3Si)2CH]2M· or [(Me3Si)2N]2M·(M = P or As) characterised by their e.s.r. spectra.
