Electron-Poor Pentafluorophenyl-Substituted PCP−Palladium Pincer Complexes

A novel fluoroaryl-substituted PCP ligand has been synthesized and used to generate the corresponding Pd complexes. The bonding of the fluoroaryl phosphine has been investigated by X-ray crystallography, NMR spectroscopy, and a competition experiment, which indicate that the ligand is sterically comparable to its well-known phenyl analogue but clearly imparts significant electronic differences to the metal center.
