• Dihydroindazol-4-one
• Semmler-Wolff aromatization
• Acetic anhydride
• Sodium iodide

A simple and efficient procedure for the syntheses of 4-acetamido-1-arylindazoles from corresponding 1-aryl-6,7-dihydro-5H-indazol-4-one oximes by Semmler-Wolff aromatization using acetic anhydride and sodium iodide is reported.
