实验步骤: A solution of 31.25 g. (0.20 mole) t-butylcyclohexanol in 80 ml. of ethyl ether was cooled to 10° C. To this was added dropwise, with stirring, a solution of 21.0 g. (0.07 mole) sodium dichromate dihydrate and 15.75 ml. (0.30 mole) concentrated sulfuric acid in 100 ml. water while maintaining the reaction mixture below 25° C. The mixture was then warmed to room temperature, stirred for two hours, poured onto ice-water, ether layer separated, the aqueous phase extracted again with ether and the combined extracts washed with water, sodium bicarbonate and dried (MgSO4). Evaporation of the ether afforded 30.6 g. (99%) of the desired ketone. To this was added dropwise stirred for two hours separated the aqueous phase extracted again with ether the combined extracts washed with water, sodium bicarbonate dried (MgSO4) Evaporation of the ether afforded 30.6 g
