Chapter 23, Problem 60IP

Interpretation Introduction

Interpretation:

The initial product of the reaction, mechanism and the transition state of the

Rearrangement has to be drawn.

Concept Introduction:

There are mainly three types of pericyclic reactions,

1. 1) Electrocyclic reactions
2. 2) Cycloaddition reactions
3. 3) Sigmatropic reactions

[3,3]-sigmatropic rearrangement involving the conversion of allyl vinyl ether to an unsaturated carbony compound. This reaction is known as Claisen rearrangement reaction.

Stille coupling reaction: The reaction that involves coupling of an aryl, benzyl or vinyl halide or triflate with stannane in presence of $\text{Pd}{\left({\text{PPh}}_{\text{3}}\right)}_{\text{4}}$.
