As our catalyst optimization would rely on calculated ligand features, a comprehensive descriptor library was constructed incorporating bisphosphine ligands that are commercially available or prevalent in the literature, along with synthetically accessible derivatives (>550 ligands including >200 that are commercially available). This database was inspired by seminal contributions from Fey and coworkers. We set out to construct a bisphosphine descriptor library that would be applicable to reactions with varying ligand coordination environments. The resulting parameters needed to be comparable across bisphosphine ligand scaffolds with varying symmetries (C1, C2, etc.) so that disparate bisphosphine ligands could be meaningfully compared. Additionally, ligand enantiomers would require specific parameters to allow prediction of their performance on chiral substrates.
