溴代环丙烷(Bromocyclopropane),CAS 号 4333-56-6,是一种含三元环结构的卤代环烷烃,分子式 C₃H₅Br。常温下为无色透明液体,具刺激性气味,易溶于乙醚、乙醇等有机溶剂,难溶于水,沸点约 69-70℃,密度 1.51g/cm³。
其分子中三元环存在较大环张力,溴原子易参与亲核取代反应,是有机合成中构建环丙烷结构的重要中间体。可通过与金属试剂(如镁生成格氏试剂)反应,引入环丙基基团,用于合成药物分子(如抗菌剂、环丙烷类农药)及天然产物。
此外,环张力使溴代环丙烷在加热或催化剂作用下易发生开环反应,生成烯丙基溴等衍生物,应用于烯烃合成。储存需密封避光,远离热源与氧化剂,操作时需通风防护。作为环丙烷衍生物的基础试剂,在医药、农药合成领域应用广泛。
