Abstract: 6- Bromoisoflavone was prepared from 4- bromoresorcinol. Debromination reaction was found in the acylation of the starting material by using BF3 as catalyst, and a by-product, 4,6-dibro-moresorcinol, was also isolated. The reaction mechanism probably involves a bromonium ion.

Key words: 6-Bromoisoflavone, Debromination, Bromonium ion
