The synthesis of fluorinated carboxylic acids and derivatives thereof has attracted much attention due to their manifold industrial applications for instance as emulsifying agents [1]. These compounds can be prepared by electrolytic fluorination of the parent hydrocarbon compounds [2], oxidative cleavage of perfluorinated olefins [3], by ring-opening addition of hexafluorooxetane to fluorine containing acyl fluorides [4] or in reactions of perfluoroalkyl iodides with carbon dioxide [5].
