The functionalization of internal olefins has been a challenging task in organic synthesis. This protocol provides an efficient and transition‐metal‐freedirect oxidative C(sp2)−H/C(sp3)−H cross‐coupling method to access tetrasubstituted olefins. The push–pull effect from the polarized olefin substrates accelerates the internal olefin C−H alkylation. Importantly, the mechanistic experimental results
