Alcohols, oxidizing reagents oxymercuration,

Perhaps the most utilized transformation of organoboranes is their oxidation to alcohols, accomplished with basic hydrogen peroxide (H2O2, NaOH). The active reagent is the hydroperoxide anion (HOO ). Alkenes are converted to alcohols with a Markovnikov orientation (the OH group is on the more substituted carbon of the C=C moiety) of the OH group via either acid catalyzed addition of water or oxymercuration (sec. 2,10.A,B).
