Chapter 18, Problem 18.43P

Interpretation Introduction

Interpretation:

The product of the reaction between ethynyltrimethylstannane $\left(\text{HC}\equiv \text{C}-\text{Sn}{\left({\text{CH}}_{\text{3}}\right)}_{\text{3}}\right)$ and phenyl triflate $\left(\text{PhOTf}\right)$, in the presence of $\text{Pd}{\left({\text{PPh}}_{\text{3}}\right)}_{\text{4}}$ and excess $\text{LiCl}$ is to be stated.

Concept introduction:

The stille reaction is an example of coupling reaction. In stille reaction, the triflate reacts with trimethylstannane in presence of $\text{Pd}$ catalyst and $\text{LiCl}$ gives the coupling of hydrocarbon parts of trimethylstannane and triflate.
