The complexity of the deprotonation pathways, as well as their similar kinetic barriers, makes it challenging to directly determine their relative contributions to the overall reaction mechanism. To address this, we probed the DFT-supported mechanistic hypothesis involving radical anion propagation through experimental kinetic studies (Fig. ). These experimental results were then compared to microkinetic modelling (MKM) simulations using the DFTcomputed Gibbs energies and activation barriers.
