Hydrazones are very useful [[molecule]]s to do some reactions. For example, a ketone can be [[reduction|reduced]] down completely if made into a hydrazine and then treated with [[sodium ethoxide]] ([[Wolff–Kishner reduction]]). Hydrazones are very important [[intermediate]]s in many reactions, such as the [[Fischer indole synthesis]]. This makes [[indole]]s, groups which are found in many [[drug]]s. | Hydrazones are very useful [[molecule]]s to do some reactions.
