4-Cyclohexylcyclohexanol → (1,1'-Bicyclohexyl)-4-one

温度

0 °C

To a solution of 4-hydroxycyclohexylcyclohexane (25 g) in acetone (250 ml) was added dropwise with stirring 2.67N Jone's regend (77 ml) at 0° C. The mixture was then stirred for 1 hour at 0° C. The organic layer was collected and evaporated. The reaction mixture was added to a mixture of water and diethyl ether. The organic layer was washed with water, sodium hydrogen carbonate solution and brine. The organic layer was taken and dried over magnesium sulfate. The magnesium sulfate was filtered off, and the filtrate was concentrated under reduced pressure to give 4-cyclohexylcyclohexanone (19.57 g).
