摘要：

Bromination of o-hydroxyacetophenones (I) and 2'-hydroxychalcones (IV) with KBr-KBrO3 in glacial acetic acid medium gave corresponding nuclear substituted 3-bromo-2-hydroxy-acetophenone (II) and 3'bromo-2'-hydroxychalcone(V) derivatives respectively. However, bromination of 2'-hydroxy- 5'-methylchalcone (IVc) resulted in 8-bromo-6-methylflavanone (VI). All the synthesised compounds have been characterised by elemental analysis and spectral data.
