Concept introduction:
The hydroboration-oxidation reaction of an alkene is the overall syn addition of the water molecule across the double bond via anti-Markovnikov regiochemistry. The first step of the mechanism is the syn addition of borane across the carbon-carbon double bond. A deuteron from borane is added to the more substituted carbon of the double bond, and the remaining fragment is added to the less substituted carbon to form alkyl borane. The second step is the conversion of the alkyl borane to alkyl borate ester by the action of alkaline
