Chapter 24, Problem 24.68P

Interpretation Introduction

Interpretation:

The product of the given reaction is to be drawn, assuming that it takes place via an $\left[\text{8+2}\right]$ cycloaddition.

Concept introduction:

An $\left[\text{8+2}\right]$ cycloaddition reaction involves eight electrons, one from one $\text{π}$ system and two from the another. This can be achieved by the four $\text{C=C}$ bonds in the first molecule and the one $\text{C=C}$ bond in the second molecule.
