The peroxide dianion reacts with CO2 in polar aprotic organic media to afford the hydroperoxycarbonate and carbonate radical anions. These highly reactive species, if formed in lithium–O2 cells, can lead to cell degradation via oxidation of the electrolyte and electrode.

Abstract In the presence of oxygen, radiolytically generated carbonate radical anions, CO3 •–, were reacted with methyl β-D-cellobioside and methyl β-D-glucoside. From the ensuing product pattern, it was concluded that CO3 •– abstracts hydrogen atoms predominantly from glucosidic C1–H bonds. This high intramolecular selectivity was rationalised mainly in terms of a polar effect on the transition state of the hydrogen abstraction reaction. The present findings are in sharp contrast to the relative inertness of CO3 •– towards glucosidic C1–H bonds previously observed in cotton linters. The reasons for this discrepancy are discussed in light of a possible future role of CO3 •– as a bleaching agent for pulp.
