Hydrogenation of 1-alkenes catalysed by anchored montmorillonite palladium(II) complexes: a kinetic study

Hydrogenation of 1-hexene, 1-heptene and 1-octene was carried out using anchored montmorillonitebipyridinepalladium(II) acetate (C^sub I^), montmorillonitebipyridinepalladium(II) chloride (C^sub II^) and montmorillonitediphenylphosphinopalladium(II) chloride (C^sub III^) in THF. Under the reaction c...

Description
Summary:Hydrogenation of 1-hexene, 1-heptene and 1-octene was carried out using anchored montmorillonitebipyridinepalladium(II) acetate (C^sub I^), montmorillonitebipyridinepalladium(II) chloride (C^sub II^) and montmorillonitediphenylphosphinopalladium(II) chloride (C^sub III^) 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: C^sub I^ > C^sub II^ > C^sub III^. Thermodynamic and activation parameters were evaluated. A rate law and a plausible mechanism has been proposed.[PUBLICATION ABSTRACT]
