Versuchsvorschrift

Sodium benzenesulfinate (3.0 g) was added to a solution containing 1.52 g of 4-methyl-2-cyclohexen-1-one and 9 ml of water. 1N Hydrochloric acid (18 ml) was added dropwise to the resulting solution. After stirring at room temperature for 24 hours, the crystals so precipitated were filtered and washed with water, isopropanol and cold ether. After recrystallization from isopropanol, 4-methyl-3-(phenylsulfonyl)-cyclohexan-1-one was obtained in the form of white crystals (yield: 72%).
