Electrochemical activation of freons and their joint conversion with sulfur and carbon dioxides

The results are presented of a study of the electrochemical activation and dehalogenation of geminal (CF 3 CCl 3 , CF 3 CClBr 2 ) and vicinal (CF 2 ClCFCl 2 , CF 2 BrCF 2 Br, CF 2 BrCFClBr) Freons and their joint conversion with sulfur and carbon dioxides with the formation of fluorine-containing sulfinic and carbonic acids. The influence of the conditions for carrying out these reactions (structure of the Freons, the electrolysis regime, the nature of the medium, electrode materials, electron transfer mediators, etc.) on their path and the yields of the targeted products are elucidated.
