The Correct Option is B
Solution and Explanation
The reaction sequence involves a nucleophilic substitution followed by an electrophilic addition:
- sec-BuLi (sec-butyllithium) acts as a base, deprotonating the thiol group in the initial structure.
- The phenyl group (Ph) attaches to the deprotonated site via the bromine atom (Br), forming an alkylated intermediate.
- The intermediate undergoes a reaction with mercury sulfate (HgSO4) and aqueous sulfuric acid (H2SO4), facilitating the formation of a carbocation.
- Finally, in the presence of methanol (MeOH) and BF3·Et2O, an ether (OCH3) group is added to the carbocation site, completing the transformation.
