Description

5-Bromo-1-indanone is a starting compound for indanone-based pharmaceuticals. At the same time, it is also the raw material used in the synthesis. The application is an useful organic synthesis building block. Its synonym are:

5-BROMOINDAN-1-ONE;5-BROMOINDANONE;5-BROMO-1-INDANONE;1-Indanone, 5-bromo-;5-Bromo-1-indanone,98%;5-Bromo-1-indanone 98%.

Bromination of 4-bromoindanone and 5-bromoindanone, facile synthetic access to 3,5,10-tribromo-7H-benzo[c]fluoren-7-one. Bromination reactions of 5-bromoindanone were presented in the experiment and its optimum reaction conditions. 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.
