Several aldehyde and ketonephenylhydrazones were electrooxidized in MeOH. Electrooxidation in the presence of KI or tetraethylammonium p-toluenesulfonate as the supporting electrolyte afforded the corresponding methoxy(phenylazo)alkanes. whereas electrooxidation in the presence of KI, NaCN, and HOAc afforded the cyano(phenylazo)alkanes.
几种醛和酮苯腙在 MeOH 中被电氧化。在 KI 或对甲苯磺酸四乙基铵作为支持电解质的情况下进行电氧化,得到相应的甲氧基(苯偶氮)烷烃。而在 KI、NaCN 和 HOAc 存在下的电氧化得到氰基(苯偶氮)烷烃。
