Electrochemical fluorination using halogen mediators in ionic liquid hydrogen fluoride salt

In order to utilize ammomium halides (Et4NX, X=Cl, Br, I) as halogenmediator for electrocatalytic fluorination, cyclic voltammetry measurements of the halides were investigated. The catalytic current of the halides in the presence of a dithioacatal compound was observed and the macro-scale electrolysis of dithioacetals using the halogen mediator was also carried out in ionic liquid hydrogen fluoride (HF) salt to give the corresponding fluorinated products in excellent yields. The recycle use of the halogen mediator in the electrochemical fluorination was successfully demonstrated. More inexpensive halides such as potassium bromide and potassium iodide could be soluble in HF salt and worked well as halogen mediator for the electrocatalytic fluorination.

Recyclable polymer-supported iodobenzene-mediated electrocatalytic fluorination in ionic liquid

The electrochemical fluorination of organosulfur compounds in triethylamine/hydrofluoric acid (Et3N-5HF) 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 its easy separation. Notably, the mediatory activity of the iodobenzene derivative was not appreciably changed even after 10 recycle uses.
