Piperazine derivatives exhibit unusual oxidation behavior with mercury-EDTA, leading to polymerization. Substituted piperazines, particularly 1,4-bis-substituted ones, yield piperazine-2,3-diones in high amounts.
Area of Science:
- Organic Chemistry
- Oxidation Reactions
- Heterocyclic Chemistry
Context:
- Piperazine derivatives are common organic compounds.
- Oxidation reactions are fundamental in organic synthesis.
- Mercury-EDTA is a specific oxidizing agent.
Purpose:

The process of oxidation in a chemical reaction is observed in any of the three forms:
Oxidations of Aldehydes and Ketones to Carboxylic Acids
Aldehydes readily undergo oxidation in strong oxidizing agents such as potassium permanganate and chromic acid. The oxidation can also be carried out using mild oxidizing agents such as silver oxide. In fact, aldehydes can be easily oxidized...

Alkynes to Aldehydes and Ketones: Hydroboration-Oxidation
One of the convenient methods for the preparation of aldehydes and ketones is via hydration of alkynes. Hydroboration-oxidation of alkynes is an indirect hydration reaction in which an alkyne is treated with borane followed by oxidation with alkaline peroxide to form an enol that rapidly converts into an aldehyde or a ketone. Terminal alkynes form aldehydes, whereas internal alkynes give ketones as the final product.
