Concept introduction:
The hydroboration reaction takes place with syn stereochemistry and results in a non-Markovnikov addition of water to the double bond in the alkene. The resulting product has the hydroxyl group on the less highly substituted carbon.
To predict:
The product of the reaction given showing both regiochemistry and stereochemistry.
d)
Interpretation:
The product of the reaction given showing both regiochemistry and stereochemistry is to be predicted.
Concept introduction:
In the oxymercuration-demercuration process, in the first step, the electrophilic addition of Hg2+ to the alkene gives a mercurinium ion. In the next step the mercurinium ion reacts with water to yield an organomercury product. In the last step, reaction with NaBH4 removes mercury to give a more highly substituted alcohol, corresponding to Markovnikov regiochemistry, as the product.
To predict:
The product of the reaction given showing both regiochemistry and stereochemistry
