A cheap industrial method for making trans-2-bromoindan-1-ol. Trans-2-bromoindan-1-ol represented by Formula (II) is made by hydrolysing 1,2-dibromoindane represented by General Formula (I) (where the configuration of the bromine atoms on position 1 and position 2 can be trans or cis, or it can be a mixture of trans and cis isomers). Trans-2-bromoindan-1-ol represented by Formula (II) can also be made by brominating indene to synthesize 1,2-dibromoindane, and then continuously hydrolysing this 1,2-dibromoindane without isolating it. 1,2-Dibromoindane can also be made by reacting indene with hydrogen bromide in the presence of hydrogen peroxide.
一种制造反式-2-溴茚满-1-醇的廉价工业方法。式(II)代表的反式-2-溴茚满-1-醇是通过水解通式(I)代表的 1,2-二溴茚满制成的(其中位置 1 和位置 2 上溴原子的构型可以是反式或顺式,也可以是反式和顺式异构体的混合物)。以式(II)为代表的反式-2-溴茚满-1-醇也可以通过溴化茚合成 1,2-二溴茚满,然后连续水解 1,2-二溴茚满而不分离出来。1,2-二溴茚满也可以在过氧化氢存在下通过茚与溴化氢反应制得。
