WebAlkenes can be converted to alcohols by reaction with mercuric acetate to form a β-hydroxyalkylmercury (II) acetate compound, a reaction called oxymercuration. Subsequent reduction with NaBH4 reduces the C-Hg bond to a C-H bond, forming the alkyl alcohol, a reaction called demercuration. WebOxymercuration–reduction of alkenes is one of the major reactions converting alkenes to alcohols. It involves the hydration of alkenes with mercuric acetate in a mixture of tetrahydrofuran and water, forming an organomercury adduct. This is followed by a demercuration step in which the adduct is reduced to an alcohol using sodium borohydride.
