Beschreibung

Allgemeine Beschreibung

Sodium bromide is a brominating agent mainly used in organic synthetic reactions as a bromide source.

Anwendung

Sodium bromide can be used as:

• A catalyst to synthesize tetrahydrobenzo[b]pyrans via three-component cyclocondensation of aryl aldehydes, alkyl nitriles, and dimedone under solvent-free and microwave-assisted reactions.
• A precursor to synthesize bromomethylated γ-lactones via an electrochemical process.
• A sodium bromide bath to prepare small Ag nanocubes with sharp edges.
