It is shown that the rate of hydrogenation of substituted propargyl and allyl alcohols, as measured in the liquid phase on a membrane Pd-Ru alloy catalyst is described by the two-parameter Taft equation, which accounts for the induction and steric substituent effects.A positive induction effect of the substituent group promotes the reaction, whereas a negative one slows it down; an enhancement in the steric factor decreases the rate of conversion.Both induction and steric effects are stronger in reactions with ethylenic rather than acetylenic alcohols and for trans rather than cis isomers.
