一般描述
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。
应用
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。

Polyphenylsilsesquioxane [PhSiO(1.5)](n) (PPS) and polyvinylsilsesquioxane [vinylSiO(1.5)](n) (PVS) are polymeric byproducts of the syntheses of the related T(8) octamers [PhSiO(1.5)](8) and [vinylSiO(1.5)](8). Here we demonstrate that random-structured PPS and PVS rearrange in the presence of catalytic amounts of Bu(4)N(+)F(-) in THF
