Arylpalladium complexes with a silsesquioxanate ligand. Preparation and structures in the solid state and in solution

The reaction of the incompletely condensed silsesquioxane (c-C 5H9)7Si7O9(OH) 3 with [Pd(C6H3Me2-2,4)(I)(bpy)] produced a complex with a Pd-O bond, [Pd(C6H3Me 2-2,4){(c-C5H9)7Si7O 10(OH)2}(bpy)]. Palladium complexes having a silsesquioxanate ligand, [Pd(Ar){R7Si7O 10(OH)2}(tmeda)] (Ar = C6H5, C 6F5, C6H3F2-2,4; R = c-C5H9, i-C4H9), were prepared by the reaction of the silsesquioxane R7Si7O 9-(OH)3 with arylpalladium iodo complexes, [Pd(Ar)(I)(tmeda)] (tmeda = N,N,N′,N′-tetramethylethylenediamine), in the presence of Ag2O. These complexes were characterized by multinuclear (1H, 13C{1H}, 19F{ 1H}, and 29Si{1H}) NMR spectroscopy, and the structure of [Pd(C6F5){(c-C5H9) 7Si7O10(OH)2}(tmeda)] was determined by X-ray crystallography. Temperature-dependent 1H and 19F{1H} NMR spectra revealed the dynamic behavior of the complexes on the NMR time scale.
