Abstract

Problem statement: The cathodic coupling of acetophnone was carried out in aqueous solutions containing sodium sulfate and 1-Octyl-3-Methylimidazolium Chloride ([OMIM]Cl) as supporting electrolytes. [OMIM]Cl is an ionic liquid, also serving as a co-solvent to prevent the deposition of products during electrolysis. The products are extracted with ether after electrolyses. Approach: It is shown in this study that the recycling of the aqueous Na2SO4-[OMIM]Cl electrolytes is feasible. Results: The new electrolytic process is more energy saving and environment-friendly than conventional ones. Conclusion: On the other hand, the ratios of dl-to meso pinacols formed in the electrochemical reduction of acetophenone can be more than 9, higher than ever reported for any aqueous system.
