Cyclic voltammetric measurements of 3,5-di-tert-butylcatechol, catechol, hydroquinone, tetrachlorocatechol, and tetrafluorocatechol have been utilized to determine their redox chemistry and thermodynamics in acetonitrile, dimethylformamide, dimethylacetamide, and dimethyl sulfoxide. The effects of solution acidity upon the electrochemistry of these catechols, their corresponding quinones, and their redox products have been determined. On the basis of these results, electron-transfer mechanisms are proposed. The degree of interaction between a series of metal cations and the 3,5-di-rert-butyl-o-semiquinone anion has been determined.
