| Özet |
| Bromination reactions of 4-bromoindanone and 5-bromoindanone were presented and optimum reaction conditions were introduced. 2, 2, 4-Tribromoindanone was synthesized by treatment of 4-bromoindanone with molecular bromine at room temperature in a high yield. Bromination of 4-bromoindanone with NBS, SiO2 and LiClO4 in PEG yielded the corresponding 2, 4-dibromoindanone which was reduced to 1-hydroxy-2, 4-dibromoindane. Acetylation of hydroxydibromoindane in pyridine gave the 1-acetoxy-2, 4-dibromoindane in excellent yield. The radical bromination of 5-bromoindanone with NBS at 77 C in CCl4 yielded the corresponding 3, 5-dibromoindene-1-one which was converted to 3, 5, 10-tribromo-7H-benzo [c] fluoren-7-one by thermolysis. |
