In organic chemistry, the oxymercuration reaction is an electrophilic addition reaction that transforms an alkene (R2C=CR2) into a neutral alcohol. In oxymercuration, the alkene reacts with mercuric acetate (AcO−Hg−OAc) in aqueous solution to yield the addition of an acetoxymercury (−HgOAc) group and a hydroxy … See more Oxymercuration can be fully described in three steps (the whole process is sometimes called deoxymercuration), which is illustrated in stepwise fashion to the right. In the first step, the nucleophilic double bond attacks … See more In practice, the mercury adduct product created by the oxymercuration reaction is almost always treated with sodium borohydride (NaBH4) … See more • Hydroboration–oxidation reaction • Mukaiyama hydration See more Oxymercuration is very regioselective and is a textbook Markovnikov reaction; ruling out extreme cases, the water nucleophile will always preferentially attack the more substituted carbon, depositing the resultant hydroxy group there. This phenomenon is … See more Oxymercuration is not limited to an alkene reacting with water to add hydroxyl and mercury groups.
