Origin of reactivity trends of noble gas endohedral fullerenes Ng2atC60(Ng = He to Xe)

We have computationally studied the factors governing the enhanced Diels-Alder reactivity of noble gas endohedral fullerenes Ng2@C60when Ng = Ar, Kr, and Xe as compared to Ng = none, He, and Ne. To this end, we have employed the activation strain model of reactivity in combination with the energy decomposition analysis (EDA) method in DFT calculations on the Diels-Alder cycloaddition reaction between Ng2@C60and 1,3-butadiene. Our results indicate that when heavier noble gas dimers are introduced inside the C60cage, dramatic effects on both the geometrical and electronic structure of the fullerenic cage occur leading to a remarkable enhanced interaction between the deformed reactants along the entire reaction coordinate
