Abstract:4-(4-Hydroxyphenyl) cyclohexanone was prepared from p-bromophenol, trimethylchlorosilane, magnesium chips and 1,4-cyclohexanedione monoethylene glycol ketal through a series of reactions including hydroxyl protection, Grignard reagent preparation, Grignard ketone addition reaction, dehydration to alkene, and one-step hydro-deprotection to ketone. The structure of the target compound was characterized by 1H NMR. The yield of the target product was 76.8%. This route has the advantages of simple operation, high yield, environmental friendliness and is suitable for industrial production. |
Key words:hydroxyl protection; Grignard reagent; hydrogenation reduction; 4-(4-hydroxyphenyl) cyclohexanone |
