N-Bromosuccinimida

Descripción:

N-Bromosuccinimida (NBS) es un compuesto químico con la fórmula molecular C4H4BrNO2. Aparece como un sólido cristalino blanco a amarillo pálido y se utiliza comúnmente como agente brominante en la síntesis orgánica. NBS es especialmente valorado por su capacidad para brominar selectivamente alquenos y compuestos aromáticos en condiciones suaves, a menudo en presencia de luz o calor. El compuesto es soluble en disolventes orgánicos como acetona y cloroformo, pero tiene una solubilidad limitada en agua. NBS es estable en condiciones normales, pero puede descomponerse al exponerse a la humedad o al calor, liberando bromo. A menudo se utiliza en reacciones radicales, donde genera radicales de bromo, facilitando diversas transformaciones en la química orgánica. Se necesitan precauciones de seguridad al manipular NBS, ya que puede ser un irritante para la piel y el sistema respiratorio, y su contenido de bromo presenta peligros potenciales. En general, N-Bromosuccinimida es un reactivo versátil en la química orgánica sintética, que permite la introducción de bromo en una amplia gama de sustratos.

N-Bromosuccinimide is a reactive chemical that is used in the manufacture of pharmaceutical preparations. It reacts with methyl ketones to form bromoketones, which can be detected by the chemiluminescence method. Although there is no direct evidence for the mechanism of this reaction, it is thought that there are two possible pathways. The first pathway involves a series of reactions involving activated methylene compounds and quinoline derivatives, while the second pathway involves transfer reactions from n-dimethyl formamide to lysine residues in proteins. The second pathway has been shown to be dominant in aerobacter aerogenes.
