malonic ester anion () in DMF to give (), 1-hydroperfluoroalkane () and dimer of the anion (). The reaction is accelerated by UV irradiation and partly suppressed by p-DNB. Diallyl ether (DAE) can trap the radical intermediates to afford five-membered ring products. Interestingly, in the case of ( X = Cl, I ) the same reaction mainly yielded tetrafluoroethylene and instead of and . The radical intermediate

The structure of a tungsten(II) methylene complex, [Tp′(CO)(PhCCMe)WCH2][BAr′4] (2a), was obtained by taking advantage of the stabilizing, weakly coordinating counterion, BAr′4−, to form X-ray quality single crystals. The electrophilic reactivity of [Tp′(CO)(PhCCMe)WCH2][PF6] (2b) was surveyed with both neutral nucleophiles (triphenylphosphine and pyridine) and anionic nucleophiles (formed by deprotonation
