predict the major products of the following reactions
Predict the major products of the following reactions. Include stereochemistry where applicable.
(a) 1-methylcycloheptene + BH3 · THF, then H2O2, OH−
(b) trans-4,4-dimethylpent-2-ene + BH3 · THF, then H2O2, OH−
Homework Answers
(a)
1-methylcycloheptene undergoes hydroboration in presence of 
to form alkyl boranes.
The alkyl borane undergoes oxidation in presence of 
to form an alcohol.
(b)
Trans-4,4-dimethylpent-2-ene undergoes hydroboration in presence of 
and followed by oxidation in presence of 
to form an alcohol as product.
Due to the unsymmetrical nature of trans-4,4-dimethylpent-2-ene, two products are formed on hydroboration and followed by oxidation.
(c)
Bicyclic alkene undergoes hydroboration in presence of 
and followed by oxidation in presence of 
to form an alcohol as product.
