Transfer Hydrogenation of Carbon Dioxide and Bicarbonate from Glycerol Under Aqueous Conditions

Abstract

The transfer hydrogenation of CO2 from glycerol to afford formic and lactic acid is a highly attractive path to valorizing two waste streams, and is significantly more thermodynamically favorable process than direct CO2 hydrogenation. We report the first homogeneous catalyst for this transformation, consisting of water-soluble Ru N-heterocyclic carbene complex. The catalyst affords lactic and formic acid selectively in the presence of base at temperatures between 150 and 225 ˚C. Carbonate salts can also be utilized in place of CO2, affording the same products at higher rates.
