Two steps were observed in the electrochemical oxidation of organyl-2,2-dichlorovinyl sulfides R-S-CH=CCl2, Macroscale electrolyses gives, respectively the sulfoxides (at the first step) and the sulfones (at the second step), This method offers advantage over the chemical oxidation. With 1,2-bis(organylchalcogeno)-1,2-dichloroethylenes RY-CCL=CCl-YR (Y = S, Se, Te) selectivity was not so high, the main product being the bis-sulf(selen)oxide.
