Chapter 17, Problem 17.15P

Interpretation Introduction

Interpretation:

A complete and detailed mechanism for the reaction in Equation $\text{17-23}$ is to be determined.

Concept introduction:

The addition of Grignard reagent in ${\text{CO}}_{\text{2}}$ is a carboxylation reaction in which a new $\text{C-C}$ bond is formed. In the first step, carboxylate anion is formed by addition of Grignard reagent on ${\text{CO}}_{\text{2}}$, and on further protonation, this carboxylate ion will convert to carboxylic acid.
