(a)

Interpretation Introduction

Interpretation:

Given compound has to be prepared by Heck reaction using methyl-2-propenaote as the starting material.

Concept Introduction:

The $H$ atom on an alkene such as vinylic hydrogen is substituted by a haloalkene or haloarene is often in the presence of base and small amount of $Pd$ catalyst.

Reaction is highly regioselective in which formation of a new carbon-carbon bond occurs at a less substituted carbon of a double bond.
