Question
Chapter 28, Problem 46P
Interpretation Introduction
Interpretation:
The steps involved in the given reaction should be illustrated.
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.
In an electrocyclic reaction “one new sigma- bond is formed or brocken.”
Diels-Alder reaction is a cycloaddition reaction which is occurs between a conjugated diene and substituted
But in reverse Diels-Alder reaction, the six membered ring is break down to regenerate the diene and dienophile (substituted alkene) using high temperature.
Mechanism gives the step wise processes occurs in a particular reaction.
