Palladium fluorophenyl complexes with different pincer ligands Pd(Ar)[2,6-(tBu2PCH2)2C6H 3] (13), Pd(Ar)[2,6-(tBu2PO)2C 6H3] (14), Pd(Ar)[{2,5-(tBu2PCH 2)2C5H2}Fe(C5H 5)] (15), and Pd(Ar)[{2,5-(tBu2PCH2) 2C5H2}Ru(C5H5)] (16) were synthesized by the reaction of LiAr (Ar = C6H4F-4) with the respective trifluoroacetate palladium pincer complexes 9-12. The molecular structures of 14 and 16 were determined by an X-ray crystallographic method. Complexes 13-16 and {Pd(Ar)[{2,5-(tBu2PCH2) 2C5H2}Fe(C5H5)]}PF 6 (17) were studied by multinuclear NMR spectroscopy and cyclic voltammetry. On the basis of 19F NMR chemical shifts and 1J(13C-19F) coupling constants, as well as PdII/PdIV oxidation potentials, electronic characteristics of the corresponding pincer ligands were elucidated.
