Both, the energy and the reactivity index based models consistently complement each other to give a correct interpretation of the reactivity and selectivity patterns experimentally established for these systems.enChemical ReactivityElectronegativityParrbenzenecoppersodiumzeoliteArtículoDOI: 10.1016/j.cplett.2003.11.083
