Abstract: Bromo ketene dithioacetals (5) were prepared in high yields by reaction of α,α-diacetyl ketene dithioacetals (4) with bromine catalyzed by FeBr3 at room temperature. This new reaction is proposed involving an ipso electrophilic addition-deacetylation mechanism.

Key words: Bromodeacetylation, α-Bromo ketene dithioacetals, α,α-Diacetyl ketene dithioacetals
