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 ...
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

Swimmer puppy syndrome is a rare condition in which dogs are born flat on their chests and abdomens, leaving them with spread eagled legs. This deformity leaves the canine unable to stand or walk. The British Bulldog is the dog breed that it found to suffer from the condition the most. [1]
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.
Tetrakis(acetoxymercurio)methane [5]. In part reflecting the strength of the C-Hg bond, organomercury compounds are generated by many methods. [6] Indeed, mercury may adsorb onto laboratory glassware, such that laboratories performing mercury experiments may have difficulty avoiding C–Hg bond formation.
In organic chemistry, endo–exo isomerism is a special type of stereoisomerism found in organic compounds with a substituent on a bridged ring system. [1] The prefix endo is reserved for the isomer with the substituent located closest, or "syn", to the longest bridge.
Personality traits of dogs affect both their ability to be successfully trained and their ability to successfully track. Dogs that are more active and confident tend to perform better during training activities and tracking activities. [12] The mannerisms of the handler [13] working with the dog can also affect tracking ability.
