Abstract
1,1,3,3-Tetrabromoindane and 1,1,2,3,3-pentabromoindane were efficiently sy nthesized by photolytic bromination of indane. Subsequent dehydrobrominatio n of them gave the corresponding tribromo- and tetrabromoindenes, which wer e easily converted to the corresponding bromoindenones by silver-supported hydrolysis. Thermolysis of 3-bromoindenone gave the benzo[c]fluorenone deri vative. (C) 2001 Elsevier Science Ltd. All rights reserved.
