一般描述
乙烯基溴属于卤代烯 ，由于未饱和乙烯基的存在，具有很高的反应活性。在加入聚合物或材料的结构中时，它可以为聚合物或材料带来阻燃性。它也是一种多功能的结构单元，可用于聚合、加成反应、取代反应和交联反应，如Suzuki-Miyaura 和Negishi反应。 它可用于将放射性标记引入医学成像用分子。
应用
- 在电子转移介质存在下，乙烯基溴的电化学还原对二氧化碳进行序贯乙烯基环化/固定：本研究探讨了乙烯基溴的电化学还原，重点关注乙烯基自由基环化和二氧化碳固定（A Katayama, H Senboku, 2016）。
- 氩气基质中臭氧与溴乙烯和氟化物波长相关光化学反应的比较：该研究比较了乙烯基溴和氟化物与臭氧的光化学反应，考察了它们在氩气基质中的特性（BS Ault, 2021）。
乙烯基溴溶液可用作前体，用于通过不对称还原偶联，进行手性2-乙烯基四氢萘的立体选择性合成。这些手性化合物是天然产物、农用化学品和液晶中的重要结构单元。

An iron-catalysed, hydride-mediated reductive cross-coupling reaction has been developed for the preparation of alkanes. Using a bench-stable iron(II) pre-catalyst, reductive cross-coupling of vinyl iodides, bromides and chlorides with aryl- and alkyl Grignard reagents successfully gave the products of formal sp(3)-sp(3)
