α-溴代二硫缩烯酮的制备及其反应
Preparation and Reaction of α-Bromoketene Dithioacetals
【Abstract】 Bromo ketene dithioacetals (5) were prepared in high yields by reaction of α,α-diacetyl ketene dithioacetals (4) with bromine catalyzed by FeBr 3 at room temperature. This new reaction is proposed involving an ipso electrophilic addition-deacetylation mechanism.
