A novel method for the oxidative radical azidation of alkenes relies on an azide in combination with a hypervalent iodine reagent. A cascade of CN and CC bond‐forming reactions yields 2‐oxindoles under metal‐free conditions with high reaction rates at ambient temperature and provides access to complex products (see scheme; TMS=trimethylsilyl).
用于烯烃的氧化自由基叠氮化的新方法依赖于叠氮化物与高价碘试剂的组合。CN和CC键形成反应的级联反应在无金属条件下在环境温度下以高反应速率生成2-吲哚,并提供了获得复杂产物的途径(请参阅方案; TMS =三甲基甲硅烷基)。
