3-(4-Methoxyphenyl)-2-cyclohexen-1-one → 3-(4-Methoxyphenyl)cyclohexanone

Participants

Reaction Steps

1.5 g of 5% palladium on active carbon are added to 15.15 g of 3-(4-methoxyphenyl)-2-cyclohexen-1-one in 400 ml of methanol and stirring is carried out in a hydrogen atmosphere for 4 hours. The catalyst is filtered off and the reaction mixture is concentrated. The mixture so obtained is dissolved in 200 ml of dichloromethane and stirred with 26.9 g of pyridinium dichromate and 2.1 g of pyridinium trifluoroacetate at room temperature for 6 hours. The reaction mixture is decanted, concentrated and purified over silica gel. 3-(4-Methoxyphenyl)cyclohexanone is obtained in the form of a colourless oil.
