“…A most careful analysis of the products and of their distribution for the macro-reduction of acetophenone was carried out by L.J.J. Janssen using a graphite cathode [25], DL-pinacol and meso-pinacol being the main products. A very low yield of phenylethanol was also obtained.…”

In order to test if it were possible to use a spe in industrial organic electrosynthesis, we studied the synthesis of 1-phenylethanol through the electrochemical hydrogenation of acetophenone using Pd/C 30% wt with different loadings as cathode and a hydrogen gas diffusion anode. A Polymer ElectrolyteMembrane Electrochemical Reactor, PEMER, with a fuel cell structure was chosen to carry out electrochemical reduction with a view to simplifying an industrial scale-up of the electrochemical process. We studied the influence of current density and cathode catalyst loading on this electroorganic synthesis. Selectivity for 1-phenylethanol was around 90% with only ethylbenzene and hydrogen detected as by-products.

“…There have been many studies concerning how to control the product-selectivity of hydrodimer to hydromonomer. Controlled potential electrolysis is generally effectual (Kodama et al, 2001;Janssen, 1988). Alternatively, a better mass-transfer condition can favor the production of hydrodimer under galvanostatic operation (Cheng and Nonaka, 1989;.…”

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 Na 2 SO 4-[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.
