Chapter 24, Problem 47P

Interpretation Introduction

Interpretation: A synthesis of diene A from $\left(Z\right)\text{-2-}$ bromostyrene as the only organic starting material is to be stated.

Concept introduction: The treatment of an organic halide $\left({\text{R}}^{\text{'}}\text{X}\right)$ with an organoborane reagent $\left({\text{RBY}}_{\text{2}}\right)$ in the presence of $\text{Pd}$ catalyst to afford the $\text{C}-\text{C}$ coupling is known as Suzuki reaction. The metal catalyst is coordinated with some ligands, like ${\text{PPh}}_{\text{3}}$. The reaction is facilitated in the presence of strong inorganic base like ${\text{NaOCH}}_{\text{2}}{\text{CH}}_{\text{3}}$ or $\text{NaOH}$.
