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).
