Procedure

To a 0.67 M solution of the benzaldehyde (20.0 mmol) and cyclohexanone (10.0 mmol) in ethanol (15 ml) is added 10 ml 40% KOH at 10° C. After stirring for 12-24 hr at room temperature, the solution is diluted and filtered. The precipitate is recrystallized from ethanol to afford 2,6-dibenzalcyclohexanone and its derivatives.
