Approximate mechanistic modeling was performed using short 50 fs GFN2-xTB steered molecular dynamics simulations, where restraints on the reaction coordinate, e.g., constraints on the lengths for forming and breaking bonds, were gradually turned on and off during the simulation duration. In total, this produced ~20k so-called reactive conformers that were added to the training dataset. It is worth noting that the number of samples describing reactive chemistry is only a small fraction of the total AIMNet2-Pd dataset, however, it is found to be sufficient for producing a transferable AIMNet2-Pd model for the varied cross-coupling mechanistic steps.
