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
