To construct the reaction network, interleaved product enumeration and transition state localization was performed as described in the previous sections until exhausting the discovery of new reactions. At each stage of this iteration, the Ga-products of the previous iteration served as potential reactants for the next iteration subject to conditions that were designed to manage the size of the reaction network while being relatively permissive in terms of exploring new reactivities. Specifically, Ga-species were only included as potential reactants at the next iteration if they were connected to the rest of the network by an intended reaction with an activation energy less than 3 eV (∼ 70 kcal/mol). Additionally, the size of the reactant species attached to the gallium site was limited to butyl and smaller to avoid the trivial growth of the network due to lengthening of the carbon backbone. All of the Ga intermediates obtained without violating these constraints were included as species capable of participating in reactions in the next iteration. At each iteration, the set of explored reactants consisted of all combinations of the active Ga-species and any free olefins that were produced as products during previous iterations of exploration. Thus, a newly generated Ga-species would participate in up to n + 1 separate reactant sets, where n is the collection of free olefins discovered up until that point of exploration and the additional one corresponds to considering unimolecular reactions involving the Ga-species. Reactant combinations involving more than six carbons were discarded to avoid trivial growth of the network. For each set of reactants, the ERS generated reactions were characterized and the recursion ended after no new reactions were discovered. We note that it is possible for a Ga-species to fail the activation energy constraint at an early iteration, but then to be included later if an alternative pathway is discovered.
