Data related to Suzuki-Miyaura and Buchwald-Hartwig reactions were extracted from the HTE data set containing a total of ca. 40K entries for various chemical transformations. Reaction records where any of the reaction components was missing the information about the number of equivalents used were rejected. When possible, missing SMILES representation for reagents and solvents were added based on the provided names in the data set. Due to the data quality concerns, entries where the catalysts were missing their corresponding short-hand names were removed. Compound SMILES were then passed through the ChemAxon-based Structure Checker and Standardizer pipelines. Reactions were removed when any of their compounds had missing SMILES or failed the standardisation process. All reaction molecules but products were assigned the enrichment class IDs based on the number of equivalents for the compound and reaction temperature (Table and). The time information was ignored due to the very strong domination of one reaction time length for each of the reaction types. Only the entries with the unique combinations of reaction strings and vectors of enriching class IDs were retained. The resulting Suzuki-Miyaura set and the Buchwald-Hartwig set contained 2192 and 995 reaction entries, respectively.
