Reduction of Carbonyl Groups to Methylene Groups
Wolff-Kishner Reduction: Introduction
The first step in the Wolff-Kishner reduction is the conversion of a ketone with hydrazine into the corresponding hydrazone. Subsequently, base-catalyzed hydrogen migration followed by protonation yields the alkane. This reaction can be used to transform ketones and oxocarboxylic acids into the corresponding alkanes and carboxylic acids, respectively.
