    Dioxygenation of alkenes. In 2009, Yan and co-workers reported an efficient catalytic method for the sulfonyloxylactonization of alkenoic acids (Scheme 2) [43], which This catalytic system was applied to the bromination of alkenes by Gulder and co-workers. For example, the iodine(III)-catalyzed...

    standard method of brominating the double bond of an alkene followed by heating the vicinal dibromide product with strong base to eliminate two equivalents of hydrogen bromide. This is a two step synthesis in which the first step proceeds very rapidly and essentially quantitatively (almost 100% yield of product). In this synthesis your starting

    Similarly, alkenes can also react with halogens (X 2). For example, Bromine reacts with an alkene in the presence of carbon tetrachloride (CCl 4) to form vic-dibromide. It is a common test to determine a double bond or an alkene compound. The reaction will release reddish brown colour during the reaction.
