Chapter 24, Problem 24.42P

Interpretation Introduction

Interpretation:

The molecule that will react faster as a dienophile in a Diels–Alder reaction with $\text{buta-1, 3-diene}$ is to be determined. The reason for it is to be explained.

Concept introduction:

In a standard Diels–Alder reaction, the dienophile is electron poor. Electron-withdrawing substituents bonded directly to the dienophile carbons facilitate standard Diels–Alder reactions.
