128-08-5 Usage

Uses

In bromination of olefins; in oxidation of alcohols to aldehydes and ketones and of aldehydes to acid bromides.

Uses

N-Bromosuccinimide is a brominated succinimide used as a chemical reagent in radical substitution and electrophilic addition reactions in organic synthesis.

Purification Methods

N-Bromosuccinimide (30g) is purified by dissolving rapidly in 300mL of boiling water and filtering through a fluted filter paper into a flask immersed in an ice bath, and left for 2hours. The crystals are filtered off, washed thoroughly with ca 100mL of ice-cold water and drained on a Büchner funnel before drying under vacuun over P2O5 or CaCl2 [Dauben & McCoy J Am Chem Soc 81 4863 1959]. This brominating agent has also been crystallised from acetic acid or water (10 parts), washed in water and dried in vacuo [Wilcox et al. J Am Chem Soc 108 7693 1986, Shell et al. J Am Chem Soc 108 121 1986, Phillips & Cohen J Am Chem Soc 108 2013 1986, Beilstein 21/9 V 543.]
