A new concise, facile, and efficient method for synthesis of 3‐thiophenchromone was accomplished in more than over 80% yield starting from formation of the substituted 3‐iodochromones and tetrathiophentins by Stille cross‐coupling reaction in the presence of palladium on charcoal‐catalyzed ligand‐free under mild conditions.
