Chapter 27, Problem 27.20P
Interpretation Introduction

(a)

Interpretation: The product formed from the [1,7] sigmatropic rearrangement of deuterium in the given triene is to be identified.

Concept introduction: Sigmatropic rearrangements are pericyclic reactions which involve the migration of sigma bonds. In these reactions, old sigma bonds are broken and new sigma bonds are formed.

Curved arrows aid in determining the movement and flow of electrons in the reaction. The electrons that take part in the chemical reactions are shown by the curved arrows.

Interpretation Introduction

(b)

Interpretation: If the given reaction proceeds in a suprafacial or antarafacial manner under thermal conditions is to be predicted.
