Question
Chapter 16, Problem 56PP
(a)
Interpretation Introduction
Interpretation:
For each of the given reactions, the product should be determined.
Concept introduction:
- Sigmatropic rearrangement reaction is a pericyclic reaction of polyenes (π-system), in which one σ-bond is formed and another σ-bond is broken and remaining π-bonds are shifting their positions. Thereby the transition state is cyclic. The mechanism of rearrangement is represented by using curved arrows.
- Cope Rearrangement is a [3,3] sigamatropic rearrangement, in which the π-system having 6 carbons and double bonds are situated at both ends.
- Claisen Rearrangement is a [3,3] sigamatropic rearrangement of allylic vinylic/arylic ethers, in which the ethers will rearranged to carbonyl compound.
(b)
