Alkene oxymercuration-demercuration: Stereospecific: Can only be anti addition – water kicks out the mercury from underneath the intermediate three-membered ring. The reaction is considered Markovnikov as it results in water addition with same regiospecificity as a direct hydration reaction. Alkene hydroboration-oxidation
In practice, the mercury adduct product created by the oxymercuration reaction is almost always treated with sodium borohydride (NaBH 4) in aqueous base in a reaction called demercuration. In demercuration, the acetoxymercury group is replaced with a hydrogen in a stereochemically insensitive reaction [6] known as reductive elimination. The ...
Conversion of 2,5-dimethylhexyne-2,5-diol to 2,2,5,5-tetramethylte-trahydrofuran-3-one. Mercury sulfate, as well as other mercury(II) compounds, are commonly used as catalysts in oxymercuration-demercuration, a type of electrophilic addition reaction that results in hydration of an unsaturated compound.
