Chapter 8, Problem 100P

Interpretation Introduction

Interpretation:

• The products of the given Diels-Alder reactions has to be predicted.

Concept Introduction:

Diels-Alder reaction:

A conjugated diene reacts with a compound containing a carbon-carbon double bond.  It is a cycloaddition reaction, where two reactants form a cyclic product.

Rule: The stabilities of carbocation are,

${\text{Benzyl cation = allyl cation = 3}}^{\circ }{\text{carbocation > 2}}^{\circ }{\text{ carbocation > 1}}^{\circ }\text{ carbocation > methyl cation > vinyl cation}$
