Chapter 26, Problem 26.2P

Interpretation Introduction

Interpretation: Reagents A and B are to be predicted.

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 reagent is transferred to form the product, while the other becomes part of reaction’s by-product.
