Chapter 19, Problem 19.34P

Interpretation Introduction

(a)

Interpretation:

The major organic product of the given reaction is to be predicted.

Concept introduction:

Lithium dialkylcuprates ${\text{R}}_{\text{2}}\text{CuLi}$ are weaker nucleophiles and undergo substitution reaction with alkyl halide. One $\text{R}$ group from ${\text{R}}_{\text{2}}\text{CuLi}$ forms a bond with electrophilic carbon, where the halide atom is attached by removing the halide as the leaving group. In case of vinyl halide, the reaction happens with retention of configuration of $\text{C=C}$ bond.
