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.

摘要 在高温和低温下研究了 5-甲氧基茚满和 5-甲氧基茚满酮的光溴化。1,2,3-三溴-6-甲氧基茚很容易通过5-甲氧基茚在低温下的光解溴化反应合成。1,1,2,3-四溴-6-甲氧基茚在77°C下通过光溴化5-甲氧基茚而获得,然后可以通过银负载水解轻松转化为2,3-二溴-6-甲氧基茚。5-甲氧基-1-茚满酮与N-溴代琥珀酰亚胺(NBS)的光化学溴化得到3-溴-6-甲氧基茚,热解后得到苯并[c]芴酮衍生物。
