Hey organic chemistry learners! Here is a little something to help you remember the hydroboration & oxidation of alkenes which is considered as a bit tricky to remember.
Here first, BH3 & THF are added and then a intermediate with -BH2 is formed. Afterwards upon adding H2O2 with NaOH the -BH2 is replaced by an -OH group. BOOM! You have an alcohol.
This reaction gives higher yield of alcohols than alkenes’ reaction with H3O+. And no carbocation rearrangements happens. So this reaction is favored in synthesis of alcohols.
And remember this! It gives an anti-Markonikov, syn product!
