Turning chemistry into information for heterogeneous catalysis

The growing generation of data and their wide availability has led to the development of tools to produce, analyze and store this information. Computational chemistry studies and especially catalytic applications often yield a vast amount of chemical information that can be analyzed and stored using these tools. In this manuscript we present a framework that automatically performs a full automated procedure consisting in the transfer of an adsorbate from a known metal slab to a new metal slab with similar packing. Our method generates the new geometry and also performs the required calculations and analysis to finally upload the processed data to an online database (ioChem-BD). Two different implementations have been built, one to relocate minimum energy point structures and the second to transfer transition states. Our framework shows good performance for the minimum point location and a decent performance for the transition state identification. Most of the failures occurred during the transition state searches needed additional steps to fully complete the process. Further improvements of our framework are required to increase the performance of both implementations. These results point to the _avoidhuman_ path as a feasible solution for studies on very large systems that require a significant amount of human resources and in consequence are prone to human errors.

This manuscript reports a DFT based study on the reaction mechanism of the borylation reaction of aryl fluoride assisted by a nickel catalyst and a base, and the kinetic modelling of such process. The presence of the base modifies the classical cross-coupling reaction mechanism, by activating the diboron and promoting a boryl transfer reaction. Off-cycle reactions, such as some bis-phosphine/mono-phosphine equilibria showed large effects on the overall kinetics. Data publicly available within the ioChem-BD databases is integrated straightforwardly into the manuscript. We also show how the ioChem-BD Reaction Energy Profile Reports tool can be used for daily work and for accelerating catalyst discovery studies.
