We describe a simple and sustainable MgBr₂‐mediated electrochemical dearomative dihydroxylation and hydroxycyclization reactions of indoles with water. MgBr₂ is used in substoichiometric amount and acts as an electrolyte and potentially as a redox mediator to indirectly oxidize the indole nucleus into a bromonium ion which is involved in the aforementioned reactions.

吲哚的电化学脱芳香二羟基化和羟基环化

我们描述了一种简单且可持续的MgBr ₂介导的吲哚与水的电化学脱芳香化二羟基化和羟基环化反应。MgBr ₂以低于化学计量的量使用，并且充当电解质并且潜在地充当氧化还原介体，以将吲哚核间接氧化成溴离子，该溴离子参与上述反应。
