Complexes of Transition Metals in Zeolites. Activation of Hydrogenation Functions of Phthalocyanine FeII Complexes by Zeolites

The liquid-phase hydrogenation of toluene by dihydrogen in the presence of zeolite-included Fe^II phthalocyanine has been studied, (effective energy of activation and pre-exponential factor 28 ± 2 kJ mol⁻¹ and 10.3 × 10⁵ g mol⁻¹ s⁻¹, respectively) and it has been suggested that the zeolite matrix takes part in the activation of the substrate via hydrogen bonding with inner atoms of the large cavity of the zeolite.
