Abstract
AbstractThe hydrogenation of some forty aromatic ketones to the corresponding alcohols has been studied in ethanol using carbon‐supported palladium as the catalyst. Zero order kinetics with respect to ketone is observed. For acetophenones electronic substituent effects may be expressed in terms of a Hammett‐Yukawa relationship with ρ = 0.7. 2‐Alkylacetophenones react very slowly. With alkyl phenyl ketones increase of size of the alkyl group causes increasing rate of hydrogenation. The adsorbed state is discussed on the basis of competition experiments.

- Computer calculations showed optimal correlation in case of a resonance parameter 1.6 (correlation coefficient 0.97). However this value is considered to be much too high for the present reaction. Failure will be due to the fact that beside electronic effects other effects are operative (see text).

/ J. Am. Chem. Soc. by Hine J. (1960)- It may be noted that the kinetics observed excludes the possibility that enolization is rate determining. Accordingly pivalophenone and acetophenone showed practically the same ratio of hydrogenation rates when using ethanol with or without alkali.
