Molecular and Immobilized Tripodal Phosphine Ligands and Their Trinuclear Palladium Complexes.

ABSTRACT: The synthesis and characterization of the tripodal phosphines RSi(CH₂CH₂PPh₂)₃ (R = Me, OMe, OEt) (1-3) is described. The ¹H NMR spectra of all phosphines display virtual coupling patterns. The ligands form the corresponding trinuclear Pd complexes [RSi(CH₂CH₂PPh₂)₃]₂(PdCl₂)₃ (4-6) with three PdCl₂ moieties sandwiched between two tripodal ligands. The complexes 4, 5, and 7 (R = OH) have been analyzed by single crystal X-ray diffraction. The coordination at the Pd center is square planar with the phosphine groups occupying trans positions. The ³¹P{¹H} MAS NMR spectra of pol
