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

A regioselective radical fluoroalkylphosphorylation of unactivated alkenes is developed by a one-pot reaction of (bis)homoallylic alcohols, phosphine chlorides, and fluoroalkyl iodides under compact fluorescence light (CFL) irradiation. This protocol employs a novel radical rearrangement of alkoxyphosphine to achieve the unusual installing of a phosphoryl in the inner side of the terminal olefins by
