Hydroboration-oxidation is a method of making alcohols from alkenes.

Explanation:

It involves the addition of "BH"_3 to an alkene, followed by oxidation with alkaline hydrogen peroxide to form an alcohol.

The reaction is a Markovnikov addition of "BH"_3 to the alkene

On oxidation of the boron intermediate, the "OH" group ends up on the less substituted carbon.

This is opposite to the position of the "OH" group in the acid-catalyzed Markovnikov addition of water to an alkene, so the reaction is often called the anti-Markovnikov addition of water to an alkene.
