Abstract

The electrochemical properties of novel reaction media, ionic liquid (IL)/supercritical CO2 (scCO2) systems, were evaluated and the electrochemical carboxylation of various organohalides in these systems was demonstrated. Voltammetric studies revealed that the CO2 solubility in an IL such as N,N-diethyl-N-methyl-N-(2-methoxyethyl) ammonium bis(trifluoromethanesulfonyl) imide ([DEME][TFSI]) increased in the presence of scCO2. The IL/scCO2 systems were found to be effective for the electrochemical carboxylation of various organohalides.
