Acid-catalyzed addition of water to an alkene yields an alcohol with Markovnikov regiochemistry
Acid-catalyzed addition of water to an alkene yields an alcohol
with Markovnikov regiochemistry. The electrophilic H+ adds to the
sp^2 carbon with the most hydrogens to yield the most stable
carbocation intermediate, which then adds water to give the product
alcohol. To avoid the possibility of rearrangement and still give a Markovnikov alcohol, alkenes can instead be treated with mercury(II) acetate in aqucous THF and then subsequently reduced with sodium borohydride. This reaction proceeds through a cyclic mercurinium ion intermediate which...
