说明

N-溴代琥珀酰亚胺(NBS)是一种有机化合物,常用作有机合成中的溴化剂。它是溴自由基的方便来源。它用于烯丙基和苄基位置的自由基溴化。此外,NBS还用作有机化学中亲电加成和亲电取代反应的试剂。

一般描述

N-Bromosuccinimide (NBS) is an organic compound commonly used as a brominating agent in organic synthesis. It is a convenient source of bromine radicals. It is used in radical bromination of allylic and benzylic positions. Additionally, NBS is also used as a reagent in electrophilic addition and electrophilic substitution reactions in organic chemistry.
 

应用

N-Bromosuccinimide can be used as a reagent:      
  • In the Wohl-Ziegler reaction (bromination at allylic positions via a radical pathway).      
  • To synthesize benzils and aliphatic 1,2-diketones from hydrobenzoins and 1,2-diols in the presence of CCl4 as a solvent.      
  • To prepare tricyclic azepino[4,5-b]indoles from indole-β-enaminoesters or β-enaminones via Pictet–Spengler cyclization.
  • To synthesize acylsilanes via oxidative hydrolysis of 2-silyl-1,3-dithianes.
多功能溴化剂。用于色氨酸的氧化反应,但酪氨酸、组氨酸和甲硫氨酸残基被氧化的程度可能较低。也可用于核糖体巯基的改性。
 

特点和优势

NBS is an easier and safer brominating agent to handle than bromine.
