일반 설명
Hydroxylamine hydrochloride (Hydroxylammonium chloride) participates in the synthesis of 1,2,4-oxadiazoles,[1] secondary amides and tertiary amides.[2]
Hydroxylamine hydrochloride (NH2OH.HCl) is a hygroscopic salt widely used as a reactant in electrophilic substitution reactions, oxidation, and reduction reactions. It is also used in the synthesis of nitriles, pyrazoles, isoxazoles, nitrones, and pyridine.
애플리케이션
Hydroxylamine hydrochloride can be used as a reactant:
- in the synthesis of primary amides from aldehydes in the presence of cesium carbonate (Cs2CO3) as a catalyst.
- in the conversion of alicyclic /aliphatic carbonyl compounds and the aromatic aldehydes into corresponding oximes.
- in the one-pot synthesis of nitriles from aldehydes in the presence of sodium sulfate (anhyd) and sodium bicarbonate catalysts.
- It can also be used as a reducing agent in the preparation of single-layer reduced graphene oxide (RGO) sheets and films.
