Hydrogen Abstraction Reaction

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.

The Stability

It has been found that the decay in dimethylformamide and dimethylformamide-water mixtures of radical anions in five of the investigated 5-nitrofurans is governed by a second-order reaction. Only the decay of the radical anion generated from 5-nitro-2-furfural III may be described by an equation including parallel first- and second-order reactions; this behaviour is evidently caused by the relatively high stability of the corresponding dianion, this being an intermediate in the reaction path. The presence of a larger conjugated system in the substituent in position 2 results in a decrease of the unpaired electron density in the nitro group and, consequently, an increase in the stability of the corresponding radical anions.
