Application
4-溴苯乙烯已用于以下研究：
- 苯乙烯乙烯基的化学和生化特性的结构活性相关性 (SAR) 研究。
- 合成具有4-代苯乙烯基取代基的倍半硅氧烷(SQ)。
- 调查光Br端自组装单层(SAMs) 在二氧化硅(111)上的光化学生长。
- 通过Heck反应合成聚(1,4-亚苯基亚乙烯基)。
- 通过烯烃交叉复分解合成硝基烯烃。
General description
4-溴苯乙烯是对卤代苯乙烯衍生物。只有当最低频率的扭转运动发生在大约80cm-1处时，4-溴苯乙烯的质子谱才显示出与平面基态结构一致的偶极耦合。在乙酸钠和Hermann催化剂存在的情况下，其可在N,N-二甲基乙酰胺中与2-溴-6-甲氧基萘进行Heck反应，得到二芳基乙烯。
