The redox potentials of sixteen substituted p-benzoquinones were measured by cyclic voltammetry. In addition to the first and the second reduction potentials, the first oxidation potential showed linear dependence on Σ(σm + σp)/2 Hammett constant for a wide range of substituents.
通过循环伏安法测量了十六种取代的对苯醌的氧化还原电位。除了第一还原电位和第二还原电位外,在广泛的取代基范围内,第一氧化电位与 Σ(σm + σp)/2 Hammett 常数呈线性关系。
