Interpretation Introduction

Interpretation:

The initial product and final product of the palladium catalyzed reaction of given compound should be identified.

Concept Introduction:

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

Cycloaddition reaction is a concerted addition reaction of two reactants to form a ring; in which two π-bonds are converted to two σ-bonds.

Diels-Alder reaction is a reaction, in which a π-system having four atoms (diene) and a π-system having two atoms (dienophile) are undergoing in cycloaddition reaction and producing a substituted cyclohexene.

The mechanism of the ring formation in the Diels-Alder reaction is drawn by using three arrows representing the shifting of π-bonds in the two π-systems in a clockwise or counter clockwise fashion, so that the ring formation will take place.
