Sodium bromide

Sodium bromide (NaBr) is an inorganic salt. It is an inexpensive source of bromide anion. It is used as anucleophilic catalyst in organic synthesis. Additionally, NaBr is a useful electrolyte in electrochemical oxidations.

Sodium bromide is used:

• As a catalyst for the microwavce assisted three-component cyclocondensation of aryl aldehydes, alkyl nitriles and dimedone for the synthesis of highly functionalized tetrahydrobenzo[b]pyrans.
• As a source of bromine radical in the preparation of bromomethylated γ-lactones via electrochemical oxidative bromination and cyclization series of alkenoic acid derivatives.
