is a bulky, strong base that performs kinetic deprotonation. At , it removes the less hindered proton. Regioselectivity: In 3-methylcyclohexanone, deprotonation occurs at the position (less substituted) or position. Note that the methyl group at creates steric hindrance at Alkylation: The resulting enolate attacks cap C cap H sub 3 cap I cap S sub cap N 2 pathway. The methyl group will prefer an -relationship to the existing -methyl group to minimize 1,3-diaxial interactions.

In 2021, problems stopped asking if a rearrangement happens and started asking which group migrates. Under $\textH_2\textSO_4$, the migratory aptitude follows: aryl > hydride > alkyl .
