Hydrogenation of 1-hexene, 1-heptene and 1-octene was carried out using anchored montmorillonitebipyridinepalladium(II) acetate (CI), montmorillonitebipyridinepalladium(II) chloride (CII) and montmorillonitediphenylphosphinopalladium(II) chloride (CIII) in THF. Under the reaction conditions 100% saturation of the carbon–carbon double bond was observed. The observed rates were first order with respect to the partial pressure of hydrogen and fractional order with respect to [substrate] and [catalyst]. The hydrogenation rates were found to be: 1-hexene > 1-heptene > 1-octene for all three catalysts. The reactivity order of various catalysts is: CI > CII > CIII. Thermodynamic and activation parameters were evaluated. A rate law and a plausible mechanism has been proposed.
