Chapter 23, Problem 57PP

(a)

Interpretation Introduction

Interpretation:

The structure for aryl triflate required to form given product should be identified.

Concept Introduction:

Preparation of organolithium: They are prepared by reaction of organohalide in presence of two equivalents of $Li$.

    $\text{R-X}\stackrel{\text{Li}\left(\text{2eq}\right)}{\to }\text{R-Li + LiX}$

Negishi reaction: It describes how the product obtained when organometallic compound containing $\text{Zn,}\text{Al}\text{and}\text{Zr}$ is coupled with organic electrophile in presence of palladium or nickel catalyst.
