An iodine‐mediated C=C double bond‐forming reaction has been established to access various fused quinolinone derivatives under transition metal‐free conditions. The present reaction is also applicable to the synthesis of fused quinolinium frameworks from the corresponding precursors and can be conducted on a gram scale.
