(a) Activation strain diagram comparing the oxidative addition of the aliphatic C–X bond versus the arylic C–X bond (X = H, Cl, CH3) by a Pd catalyst, where the transition states are indicated with a dot. Energy decomposition analysis terms of the oxidative addition of the aliphatic C–X bond versus the arylic C–X bond (X = H, Cl, CH3) by a Pd catalyst: (b) Pauli repulsion; (c) electrostatic interaction; and (d) orbital interaction.
