| titleOfInvention | A kind of method for preparing ketone by water-phase oxidation of tertiary alcohol |
| abstract | The invention discloses a method for preparing ketones by oxidizing tertiary alcohols in water phase, which comprises the following steps: adding silver nitrate, bismuth trifluoromethanesulfonate, potassium persulfate to DAPGS-750-M/H 2 O solution, and then adding tertiary alcohols , stirred at room temperature of 900-1200rpm for 24 hours, extracted with ethyl acetate, concentrated in vacuo, and separated by column chromatography to obtain the target product. ) A novel method for oxidizing tertiary alcohols to ketones in aqueous phase provided by the present invention realizes the oxidation of tertiary alcohols that are traditionally considered to be "unoxidizable". The whole reaction is carried out at room temperature, which solves the problem of reaction energy consumption. The operation is simple, the yield is high, and the purity is above 98%. The reaction medium is green and safe, with mild conditions and a wide range of substrates. Not only simple tertiary alcohol compounds can be applied, but also complex natural products can be modified by this method. |
