The cyclic voltammetry of several naphthalene peri ketones was carried out in anhydrous DMF containing TBAP. The cathodic peak potential for carbonyl reduction was found to be shifted toward a more anodic potential when carbonyl, oxygen, and sulfur groups were present in the peri position. The controlled potential electrolysis of peri diketones gave an intramolecular coupling product via a bis-anion radical.

萘围酮进行了循环伏安测定。结果发现,当羰基、氧和
硫基团存在于围位置时,羰基还原的阴极峰电位会向更高的阳极电位移动。通过双阴离子自由基对围二酮进行可控电位电解,可得到分子内偶联产物。
