Chapter 27, Problem 27.21P
Interpretation Introduction

(a)

Interpretation: The product formed by Cope or oxy-rearrangement of given starting material is to be predicted.

Concept introduction: Cope rearrangement is a thermal [3,3] sigmatropic rearrangement. This rearrangement takes place in 1,5-diene to form more thermodynamically stable compound.

Sigmatropic rearrangements are pericyclic reactions which takes place by concerted mechanism. In these rearrangements, migration of sigma bond takes place.

Interpretation: The product formed by Cope or oxy-rearrangement of given starting material is to be predicted.

Concept introduction: Oxy-Cope rearrangement is a thermal [3,3] sigmatropic rearrangement. This rearrangement takes place in unsaturated alcohol to form more carbonyl compound.

Sigmatropic rearrangements are pericyclic reactions which takes place by concerted mechanism. In these rearrangements, migration of sigma bond takes place.
