Perfluoroalkyl sulfides, from

Oxidation. The range of oxidation potential of HOF-MeCN has been extended to the direct preparation of epoxy carboxylic acids from alkenoic acids, oxidative cleavage of methyl ethers to ketones, and conversion of aryl perfluoroalkyl sulfides to the sulfones. ... 

A linear correlation of the oxidation potentials Bp of sulfides with Taft s a values of fluoromethy] groups is obtained as shown in Fig. 1 [42]. This dearly indicates that the polar effect of the fluoroalkyl group plays a significant role in the electron-transfer step from the sulfides to anode. Namely, the oxidation potential increases linearly as the number of fluorine atoms of the fluoroalkyl group increases. However, interestingly the oxidation potential was not appreciably affected by the length of the perfluoroalkyl group (Table 4).
