electrochemical Beckmann rearrangement, i. e. the direct electrolysis of ketoximes to amides, is presented for the first time. Using a constant current as the driving force, the reaction can be easily carried out under neutral conditions at room temperature. Based on a series of mechanistic studies, a novel radical Beckmann rearrangement mechanism is proposed. This electrochemical Beckmann rearrangement does
摘要:很少研究电合成作为将杂原子引入碳骨架的潜在手段。在此,电化学贝克曼重排,即。e。首次介绍了酮肟的直接电解成酰胺。使用恒定电流作为驱动力,可以在室温下在中性条件下容易地进行反应。在一系列机理研究的基础上,提出了一种新颖的自由基贝克曼重排机理。这种电化学贝克曼重排不遵循经典贝克曼重排的反迁移规则。
