WebJul 31, 2024 · For example, we would expect the conjugate acid of 2,2-dimethyloxacyclopropane to be attacked by methanol at the primary carbon by an S N 2 reaction and at the tertiary carbon by an S N 1 reaction: Because both products actually are obtained, we can conclude that both the S N 1 and S N 2 mechanisms occur.

WebExample #3 is noteworthy because the less stable trans-cyclooctene is the chief product, accompanied by the cis-isomer. An anti-E2-transition state would necessarily give the cis-cycloalkene, so the trans-isomer must be generated by a syn-elimination.
