✦ Synopsis

A series of quinones were examined electrochemically in non-aqueous electrolyte for their reactivity with carbon dioxide. The quinones were shown to react with CO, via an ECE type mechanism at much more positive potentials than aromatic hydrocarbons such as anthracene and olefins. Second order rate constants for the reaction of CO, with the quinones appear to reveal a strong correlation between nucleophilicity and reaction rate. Results of the electrochemical analysis of the reaction of benzoquinone (BQ), anthraquinone (AQ), naphthoquinone (NQ), duroquinone (DQ), and 2,6-dimethylbenzoquinone (DMQ) in DMSO (TBAP, 0.1 M) with CO, are detailed in this manuscript.
