Participants

Reaction Steps

24 g of 40% boron trifluoride/acetic acid complex was cooled with ice and a mixture of 5.6 g of 4-methylcyclohexanone and acetic anhydride was added dropwise thereto. After stirring at room temperature for four hours, approximately 50 ml of a saturated aqueous solution of sodium acetate was added thereto and the obtained reaction mixture was heated under reflux for one hour. After cooling, the reaction mixture was extracted with ether, washed with an aqueous solution of sodium hydrogencarbonate and water and dried, and ether was distilled off. The total amount of the crude 2-acetyl-4-methylcyclohexanone thus obtained was subjected to the subsequent step as such.
