A partial switch in mechanism for the partial oxidation of alcohols on nickel surfaces can be induced by substitution of gamma-hydrogens with more electronegative fluorine atoms. While exclusive dehydrogenation to acetone via beta-hydride elimination from 2-propoxide surface species is seen with 2-propanol, some dehydration to 3,3,3-trfluoropropene is observed with 1,1,1-trifluoro-2-propanol. The latter reaction involves a gamma-hydride elimination rate-limiting step.
