Interpretation Introduction

(a)

Interpretation: Product from the given starting materials using an organocuprate coupling reaction is to be synthesized.

Concept introduction: Organocuprate reagents $\left({\text{R}}_{\text{2}}\text{CuLi}\right)$ react with halides of organic compounds $\text{RX}$ to form coupling products. Only one alkyl group of the organocuprate reagent is transferred to form the product, while the other becomes part of reaction’s by-product.
