Potassium Cyanide → 3-Oxo-1-phenylcyclohexanecarbonitrile

Participants

Reaction Conditions

Reaction Steps

A mixture of 3-phenylcyclohex-2-enone (14.3 mmol), potassium cyanide (1.92 g) and trimethylamine hydrochloride (2.06 g, 21.5 mmol) in H2O (10 mL) and DMF (57 mL) was heated at 93° C. for 6 hr. After cooling down to room temperature, saturated sodium bicarbonate was added and the organic layer was separated. The aqueous layer was extracted with diethyl ether 3 times. The combined organic layers were washed with saturated sodium chloride solution, dried over magnesium sulfate, filtered and concentrated under vacuum to get 2.62 g of the crude 3-oxo-1-phenylcyclohexanecarbonitrile which was directly taken to the next step without further purification.
