Suitable conditions have been found for the dehydrogenation of methyl 12-hydroxystearate to methyl 12-ketostearate with Raney nickel. Crude reaction mixtures contained 95% product when analyzed by gas-liquid chromatography (GLC). Isolated yields were 83%. Both catalyst concentration and type strongly influence the reaction. Laboratory-made methyl 12-hydroxystearate gave significantly better yields than commercial material, but satisfactory conversions were obtained from citrate-free commercial material. The extent of the dehydrogenation was determined by hydrogen evolution and GLC. Synthetic and analytical techniques used in studying this reaction are discussed. [ABSTRACT FROM AUTHOR] |
