Aqueous 25% NaBr/H<sub>2</sub>SO<sub>4</sub> is used as the electrolyte. Regio- and stereoselective dibromination of enes is achieved. Moderate to excellent yields of the product (83–98%) is obtained depending on the substrate. Electrolyte reuse has also been demonstrated successfully using HBr in the dibromination of styrene.</p> 2016-02-09 00:16:35 Biphasic media cyclic and acyclic enes dibromide electrolytic oxidation stereoselectivity
