N－溴代丁二酰亚胺－二甲基甲酰胺系统对芳伯胺的单溴代反应

Monobromination of Primary Arylamines by NBS-DMF System

系统地研究了等摩尔比的ＮＢＳ和取代芳伯胺在无水ＤＭＦ中的单溴代反应。研究表明，ＮＢＳ－ＤＭＦ系统对芳伯胺类进行单溴代，具有反应专一，收率高，操作方便，通用性较好等优点。

The reaction between equimolar N-bromosuccinimide(NBS) and some primary arylamines in dry dimethylformamide(DMF) was systematically studied and it was found that NBS in DMF was ideal for the monobromination of primary arylamines.
