Abstract
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.Keywords
