In reductive hydrodefluorination the fluorocarbon is reduced in a series of single electron transfer steps through the radical anion, the radical and the anion with ultimate loss of a fluorine anion. An example is the conversion of pentafluorobenzoic acid to 3,4,5-tetrafluorobenzoic acid in a reaction of zinc dust in aqueous ammonia.

The O–F bond of hypofluorites is relatively weak. For trifluoromethyl hypofluorite (CF 3 OF), it has been estimated to be 43.5 kcal/mol (182 kJ/mol). [9] The ability of trifluoromethyl hypofluorite to transfer fluorine to alkyl radicals is notably demonstrated by reacting independently generated ethyl radicals from ethene and tritium in the presence of CF 3 OF.

The International Symposium on Fluorine Chemistry (ISFC) is an academic conference where researchers present their most recent original results on the chemistry of fluorine and its derivatives. Communications deal with all compounds of fluorine , from hydrogen fluoride to fluoropolymers and other fluorocarbons .
The European Symposium on Fluorine Chemistry (ESFC) is a triennial academic conference on Fluorine chemistry founded in 1965. The conference is held in Europe, but traditionally it brings together the fluorine community from all over the world. The scientific programme of the Symposium covers all the areas of fluorine chemistry relevant to ...
A convenient, safe method for generating TFE is the pyrolysis of the sodium salt of pentafluoropropionic acid: [6]. C 2 F 5 CO 2 Na → C 2 F 4 + CO 2 + NaF. The depolymerization reaction – vacuum pyrolysis of PTFE at 650–700 °C (1,200–1,290 °F) in a quartz vessel – is a traditional laboratory synthesis of TFE.
