Chapter 12, Problem 27P

(a)

Interpretation Introduction

Interpretation:

The alkyl halide which is needed to react with lithium divinylcuprate for the synthesis of given compound should be determined.

Concept introduction:

Gilman reagent: The lithium copper (diorganocopper) reagent compound $(R_{2}CuLi)$, these reagent are very useful because unlike Grignard reagent and organolithium reagents, they react with organic halides to replace the halide group with an alkyl (R) group.

Organometallic reagents such as organocuprate $(R_{2}CuLi)$ have a transition as their metal atom, they are used to form new carbon-carbon bonds.

• Organocuprate $(R_{2}CuLi)$ are also known as Gilman Reagent.
• It is prepared from an organolithium compound by reaction with cuprous iodide in diethyl ether or THF as follows.
