PROCESS FOR PRODUCING TRANS-2-BROMOINDAN-1-OL |
摘要 |
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. |
