1,1,3,3-Tetrabromoindane and 1,1,2,3,3-pentabromoindane were efficiently synthesized by photolytic bromination of indane. Subsequent dehydrobromination of them gave the corresponding tribromo- and tetrabromoindenes, which were easily converted to the corresponding bromoindenones by silver-supported hydrolysis. Thermolysis of 3-bromoindenone gave the benzo[c]fluorenone derivative.
通过茚满的光解溴可有效合成1,1,3,3-四溴茚满和1,1,2,3,3-五溴茚满。随后将它们脱氢溴化,得到相应的三溴代和四溴代茚,它们很容易通过银负载的水解转化为相应的溴代茚满。3-溴茚满酮的热解得到苯并[ c ]芴酮衍生物。
