SPhos is a phosphine ligand derived from biphenyl. Its palladium complexes exhibit high activity for Suzuki coupling reactions involving aryl chlorides, which are unreactive with palladium complexes of most other phosphine ligands. The ligand has convenient handling characteristics since it is air-stable. WebAdditionally, the reaction of SPhos·Pd and XPhos·Pd with chlorobenzene is explored via all-atom density functional theory (DFT). It has been determined that inclusion of the entire …
