Several palladium(II) 3-iminophosphine complexes were synthesized in moderate to high yield. With relevance to many palladium-catalyzed coupling reactions, these complexes incorporate a wide variety of ligands, including amines, alkyls, allyls, and triflates. The presence of both η1- and η2-coordination modes demonstrates the hemilability of the 3-iminophosphine ligand class, as determined by X-ray crystallography and NMR spectroscopy.
