Chlorocyclohexane → Tricyclohexylbenzene

Participants

Reaction Conditions

Reaction Steps

Aluminum chloride (6.83 g) was added to 20.0 g of benzene, and the mixture was cooled with stirring at 3° C. Thereto, 40.4 g of cyclohexyl chloride was gradually added dropwise. After the dropwise addition, the reaction solution was stirred at room temperature for 5 hours and then poured in ice water. The organic layer was extracted with ethyl acetate, and the obtained organic layer was distilled off under reduced pressure at 40° C. and further distilled off under reduced pressure at 170° C. The residue was cooled, to room temperature, and 50 ml of acetone was added thereto for recrystallization. The precipitated crystal was collected by filtration to obtain 14 g of tricyclohexylbenzene.
