Description

<jats:p>The double functionalization of styrenes through Cu‐mediated assisted tandem catalysis was developed. The reaction was initiated by Cu‐catalyzed aziridination and the subsequent nucleophilic ring‐opening, which was triggered by the addition of (NH<jats:sub>4</jats:sub>)<jats:sub>2</jats:sub>S<jats:sub>2</jats:sub>O<jats:sub>8</jats:sub> as an oxidant of Cu‐catalyst to form a variety of C–C and C–X bonds. The expansion to three contiguous catalytic cycles led to the synthesis of functionalized indolines by one‐pot operation.</jats:p>
