| Use | 1-(4-bromophenyl)-1-ethanol is a white crystalline solid, it is an important synthetic intermediate and can be used to synthesize drugs for the treatment of tumors. Photosensitive materials, alcohol oxidases, and probes for labeling proteins and DNA may also be prepared. |
| preparation | 1-(4-bromophenyl)-1-ethanol has many preparation methods, reduction with sodium borohydride from 1-(4-bromophenyl)-1-ethanone or 1-(4-bromophenyl)-1-acetic acid; benzyl p-bromoacetate was prepared by reacting benzyl p-bromochloride with sodium acetate in glacial acetic acid, and 1-(4-bromophenyl)-1-ethanol was obtained by alkaline hydrolysis of benzyl p-bromoacetate. In this paper, the target compound 1-(4-bromophenyl) was prepared by the reaction of p-bromobenzaldehyde as the starting material, chloroform and dimethylformamide (DMF) as the solvent under the catalysis of potassium hydroxide/methanol. -1-ethanol, and the reaction conditions of the process were optimized. The reaction formula for the synthesis of 1-(4-bromophenyl)-1-ethanol is shown below: |
