A novel Ru(II) complex containing an electron-poor, highlyfluorinated PCPArF pincer ligand has been synthesized in good yield via a transcyclometalation reaction. The complex has been fully characterized by elemental analysis, 1D and 2D NMR techniques, UV−vis spectroscopy, and cyclic voltammetry. Single-crystal X-ray structural analysis and DFT calculations were performed. The structural features

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.
