Electrochemical partial fluorination of organic compounds: 82: Anodic α-fluorination of five-membered cyclic thiocarbonates

Anodic fluorination of various kinds of five-membered cyclic thiocarbonates was carried out under various electrolytic conditions and the corresponding α-monofluorinated products were obtained in the cases of 1,3-oxathiolane-2-one and 1,3-dithiolane-2-one with high regioselectivity. On the contrary, oxidative desulfurization of cyclic thiocarbonates with a CS bond took place to provide the corresponding gem-difluorinated product and/or carbonyl compounds depending on the molecular structures of the starting thiocarbonates.
