Allenylketones are employed as coupling partners in palladium‐catalyzed oxidative cross‐coupling reactions with organoboronicacids. This reaction constitutes an efficient methodology for the synthesis of highlysubstitutedfuran derivatives. Palladium‐carbene migratory insertion is proposed as the key step in this transformation.
