Web8 feb. 2024 · The key difference between oxymercuration and demercuration is that oxymercuration involves an electrophilic addition where an alkene transforms into a neutral alcohol, whereas demercuration involves the conversion of an alkene into Hg2+ salt and an organomercury intermediate. WebAlkoxymercuration-demercuration is a two step pathway used to produce ethers that proceeds in a Markovnikov manner and is stereospecific (anti addition). The two …

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.
