코프 자리옮김
1,5-hexadiene ⇌ 1,5-hexadiene (rearranged)
개요
The Cope rearrangement is a [3,3]-sigmatropic rearrangement of 1,5-dienes that proceeds through a chair-like transition state. No bonds are broken or formed to reagents; the sigma bond migrates through the diene framework. The oxy-Cope variant (followed by keto-enol tautomerism) is particularly useful in synthesis.
일상 속 예시
The Cope rearrangement demonstrates that molecules can rearrange thermally without any catalyst or reagent, just by heating.
