Chapter 17.SE, Problem 58AP

Interpretation Introduction

Interpretation:

The products expected to be formed when benzoquinione reacts with i) 1 equivalent of 1,3-butadiene and ii) 2 equivalents of 1,3-butadiene are to be given.

Concept introduction:

When a dienophile is treated with a conjugated diene in Diels-Alder reaction, 1,4-addition of the dienophile takes place to one of the double bonds in the dienophile to give an addition product. Two equivalents of the diene, if used, will react with both the double bonds in the dienophile.

To give:

The products expected to be formed when benzoquinione reacts with i) one equivalent of 1,3-butadiene and ii) 2 equivalents of 1,3-butadiene.
