产品说明 一般描述 β-溴代苯乙烯是一种α ，β-不饱和芳族卤化物。它可以通过肉桂酸的催化Hunsdiecker反应(CHR)进行合成。 它通常用作制备取代的烯烃、相应的乙炔、以及天然化合物和抗生素全合成的前体。 应用 β-溴苯乙烯可用于一锅法制备肉桂腈。 它也可用于制备纯乙酯- Z-和 E-α ，α -二氟-4-苯基-3-丁烯酸乙酯 和1,3-二苯基-1-丁烯。 在二氯[1,1′-双(二苯基膦基)二茂铁]镍(II)催化剂存在下，它可用于与叔丁基氯化镁交叉偶联，合成β-叔-丁基苯乙烯。 它也可用于在炔烃存在下与羰基镍反应制备γ -丁-2-烯内酯。 包装 5 g in glass bottle 基本信息 | 线性分子式 | C6H5CH=CHBr | | 分子量 | 183.05 | | Beilstein | 2038495 | | EC 号 | 203-131-3 | | MDL编号 | MFCD00000185 | | PubChem化学物质编号 | 24849679 | | NACRES | NA.22 |
