It is used to prepare carboxylic acids from primary alkyl halides, lengthening the carbon In progress by two atoms. Thus, the product can be visualized as being a "substituted acetic acid." The reaction consists of three steps: generation of the enolate anion followed by SN 2 reaction with a primary...
