What is the hydroboration-oxidation reaction? Explain it with an example.

(N/A) Hydroboration-oxidation is a two-step reaction used to convert alkenes into alcohols.
Step $1$ (Hydroboration): Alkenes react with diborane $(BH_3)_2$ to form trialkylborane as an addition product.
Step $2$ (Oxidation): The trialkylborane is oxidized by hydrogen peroxide $(H_2O_2)$ in the presence of aqueous sodium hydroxide $(NaOH)$ to yield an alcohol.
Example: The reaction of propene with diborane followed by oxidation gives propan$-1-$ol.
$3CH_3-CH=CH_2 + \frac{1}{2}(BH_3)_2 \rightarrow (CH_3-CH_2-CH_2)_3B$
$(CH_3-CH_2-CH_2)_3B + 3H_2O_2/OH^- \rightarrow 3CH_3-CH_2-CH_2-OH + B(OH)_3$
In this reaction,the addition of $H_2O$ to the alkene follows the anti-Markovnikov rule,where the hydroxyl group attaches to the less substituted carbon atom.
