3‐Tribromo‐6‐methoxyindene was easily synthesized by photolytic bromination of 5‐methoxyindane at low temperature. 1,1,2,3‐Tetrabromo‐6‐methoxyindene was obtained from the photobromination of 5‐methoxyindan at 77 °C, which could then be easily converted to the 2,3‐dibromo‐6‐methoxyindene by silver‐supported hydrolysis.
