N-溴代丁二酰亚胺与环戊烯的α-溴代反应

α-Bromination of Cyclopentene with N-Bromosuccinimide

在进行环戊烯烯丙位一溴代和二溴代反应的实验时,意外合成了3,4,5-三溴环戊烯,采用1HNMR和EI-MS对其结构进行了表征,并分析了此产物生成的机理。3,4,5-三溴环戊烯可以作为合成一类新型活性染料或皮革同步鞣制染色材料的中间体。

3,4, 5-tribromo-cyclopentene was synthesized during the preparation of monobromide and dibromide for cyclopentene allylic. The structure of 3,4,5-tribromo-cyclopentene was characterized by I HNMR and EI-MS, and the mechanism for the formation of this product was briefly analyzed. 3,4,5-tribromo-cyclopentene could be applied as an intermediate for the synthesis of a series of novel reactive dyes or simultaneous tanning-dyeing agents for leather.
