Synthesis of cyclic carbonates from CO2 and diols via electrogenerated cyanomethyl anion

Abstract: The electrogenerated cyanomethyl anion reacts with diols in the presence of CO2 to yield the corresponding cyclic carbonates in moderated yields. The reported methodology has been carried out under mild conditions, avoiding any addition of classical bases, catalysts. In this communication, the effects of reaction conditions – such as supporting electrolyte, cathode material, current densities, charge amount, diol concentration – have been investigated to optimize the carbonates yield. © 2011 Society of Chemica… Show more

“…Other methods are the reactions of 1,2-diols with carbon dioxide using metallic acetates in acetonitrile 76 or by electrosynthesis [77][78] (Scheme 8-(2)), and the oxidative carbonylation with carbon monoxide using for instance palladium-based catalysts (Scheme 8- 7). [79][80] The approach involving the formation of a ketal from ethylene glycol and cyclohexanone, which then reacts in the presence of supercritical CO 2 is also a route to cyclic carbonates (Scheme 8-(3)).…”

“…Song estimated that the global demand for CO 2 ‐derived chemicals and materials would utilize up to 720 megatons of CO 2 , and Drummond already recalculated that even if this value were doubled, the total CO 2 consumed globally through chemical utilization would be about 5% of the total anthropogenic emissions. Nevertheless, CO 2 is a potential source of carbon to synthesize other substances with higher thermodynamic value, such as urea, salicylic acid (Kolbe‐Schmitt reaction), methanol (using H 2 from syngas), polymeric carbonate esters, cyclic carbonate, dimethyl carbonate, isocyanates, esters and lactones, and polycarbonate . Low molecular weight organic compounds (e.g.…”
