Reactions of Alkenes

Q: The vapor pressure of chloroform is 173.11 mm Hg at 25°C.How many grams of cholesterol, C27H46O, a n...Typical reagents are Hg2+ salts such as mercury acetate, Hg(OAc)2, in aqueous THF. Demercuration is effected by a reduction using sodium borohydride, NaBH4. If the reaction is carried out in the presence of an alcohol rather than water, then ethers are obtained via an alkoxymercurationThe NaBH4 is there to cleave the mercury acetate on the less substituted carbon for a hydrogen. I hope this makes sense.Hg(OAc)2, NaBH4, H2O. Oxymercuration-demercuration, gives Markovnikov product but the electrophile attacks the more subsidized carbon (more + charge), nucleophile is water, generally anti. Hg(OAc)2, NaBH4, ROH.

Oxymercuration - 1. Hg(OAc)2, H2O. Step 1: Mercuric acetate ionizes to some extent and the pi electrons of the alkene attack a mercury cation which attacks one the of the alkene carbons back forming a three-membered ring with Hg referred to as a Dermercuration (Reduction) - 2. NaBH4.Step 4: the carbon-Hg bond in organomercury intermediate is converted into C-H bond. The methylcyclohexanol has alcohol on tertiary carbon thus Keywords: Oxymercuration-demercuration reaction, alkenes, structure of two alkenes, yield 1-methylcyclohexanol, Hg(OAc)2, NaBH4.Question: 1) Hg(OAc)2 2) NaBH4. This problem has been solved!Alkoxymercuration Demercuration - Hg(OAc)2 , H20 / NaBH4 - Organic Chemistry. Correction: oxymercuration demercuration does NOT require sulfuric acid. Just 1. Hg(OAc)2, H2O; 2. NaBH4. summarizes alkeneHg(OAc). 4 C C + NaBH4. OH. organomercurial alcohol. In effect, alkoxymercuration-demercuration converts alkenes to ethers by add-ing an alcohol across the double bond of the alkene. C C + Hg(OAc)2.
