Procedure

The acetophenone was dissolved in 2-propanol (80 ml) then degassed for 40 min. This solution was added to the catalyst-containing flask by cannula, followed via syringe by the degassed 0.1 M solution of KOH in 2-propanol. The mixture was left at room temperature, samples being taken at intervals and examined by gas chromatography. At the small scale of operation the reaction mixture was not sparged with the nitrogen, but sparging would be used in larger scale production. Results for production of (R)-1-phenylethanol were:
