WebAcid-Catalyzed Addition of an Alcohol Mechanism. Step 1: The pi electrons of the alkene attack a hydrogen of the protonated alcohol* resulting in carbocation formation. The carbocation is a high energy intermediate making this the rate determining step (slow step) of … In practice, the mercury adduct product created by the oxymercuration reaction is almost always treated with sodium borohydride (NaBH4) in aqueous base in a reaction called demercuration. In demercuration, the acetoxymercury group is replaced with a hydrogen in a stereochemically insensitive reaction known as reductive elimination. The combination of oxymercuration followed immediately by demercuration is called an oxymercuration–reduction reaction.
