Anodic desulfurization of dithioacetals of ketones in the presence of Et3N·3HF provided the corresponding gem-difluorocompounds while dithioacetals of aromatic and aliphatic aldehydes gave gem-difluoro thioethers and monofluoro thioether, respectively.
The electrochemical fluorination of organosulfur compounds in triethylamine/hydrofluoric acid (Et3N-5 HF) with polystyrene-supported iodobenzene (PSIB) and tetraethylammonium chloride (Et4NCl) was performed successfully in an undivided cell under constant current conditions to afford the corresponding fluorinated compounds in moderate to good yields. Recycle use of the PSIB could be achieved due to

The electrosynthesis of hypervalent iodobenzene difluorides was accomplished by anodic oxidation of p-nitro- and p-methoxyiodobenzenes with Et(3)N.3HF in anhydrous acetonitrile, and p-methoxyiodobenzene difluoride was used as a mediator for indirect anodic gem-difluorination of dithioketals.
