indirect electrochemical oxidation of cyclic ketones in methanol in the undivided cell in the presence of sodium iodide depends on the ring size. Cyclopentanone affords 2,2-dimethoxycyclopentanone. While cyclohexanone gives rise 2,2-dimethoxycyclo-hexanol, and cyclic ketones with higher ring size undergo new type of the electrochemically induced Favorskii rearrangement with the formation of methyl cycloalkencarboxylates
在碘化钠存在下,未分裂的单元格中的甲醇中的环酮间接电化学氧化的结果取决于环的大小。环戊酮提供2,2-二甲氧基环戊酮。虽然环己酮会生成2,2-二甲氧基环己醇,但具有较高环尺寸的环酮会进行新型的电化学诱导的Favorskii重排,形成的环中含环己羧酸甲酯的碳原子数少于起始酮。因此,简单的电催化系统可以区分环状酮的环大小。
