| titleOfInvention | Method for preparing 5-hydroxy-1-indanone |
| abstract | The invention provides a method for preparing 5-hydroxy-1-indanone, which comprises the following steps: dissolving anisole and 3-chloropropionyl chloride in dichloromethane to obtain a multi-component mixture AlCl 3 /LiCl、AlCl 3 /LiCl/NaCl、AlCl 3 LiCl/NaBr or AlCl 3 Reacting at room temperature for 8-15 hours under the catalysis of LiCl/NaI Lewis acid catalyst to prepare an intermediate 3-chloro-4' - (methoxyl) propiophenone, and evaporating dichloromethane; then heating to 100-170 ℃ melting state, continuing to react for 4-8 hours, cooling, pouring the reactant into ice water, adjusting the pH to 3-5 with hydrochloric acid, extracting with ethyl acetate, drying the organic phase, removing the solvent, and purifying to obtain the 5-hydroxy-1-indanone. |
