Question
Chapter 28.5, Problem 14P
Interpretation Introduction
Interpretation:
It should explained that why was a deuterated compound used in the given reaction.
Concept introduction:
Pericyclic reactions are “ any concerted reaction in which bonds are formed or brocken in a cyclic transition state”. There is a single transition state from start to finish, in contrast to a stepwise reaction.
There are mainly three types of pericyclic reactions,
- 1) Electrocyclic reactions
- 2) Cycloaddition reactions
- 3) Sigmatropic reactions
In a sigmatropic reaction “ one new sigma-bond is formed as another breaks.”
Sigmatropic rearrangement reactions are named with digits. For example a [1, 3] sigmatropic rearrangement describe a reaction in which the residue migrates from position 1 to position 3.

A student claims the right-hand side of the reaction in the drawing area below shows the product of a Claisen condensation.
• If the student is correct, complete the reaction by adding the necessary organic reactants to the left-hand side, and by adding any necessary reagents and
reaction conditions above and below the arrow.
• If the student is incorrect, because it's not possible to obtain this product from a Claisen condensation, check the box under the drawing area instead.
