Abstract

The central phosphino group of tripodal tetradentate tris[2- (diphenylphosphino)ethyl]phosphine (pp₃) was selectively oxidized by the reaction with diethyl disulfide to give tridentate phosphine ligand pOp ₃. The terminal phosphino groups were reacted with sulfur to give pOp₃ trisulfide (pOp₃S₃). Three palladium(II) ions were sandwiched in the two pOp₃ and pOp₃S₃ ligands to form the trinuclear complexes with three trans(P) and trans(S) PdX₂ (X = Cl, Br, I) moieties, respectively. The tripodal triphosphine, 1,1,1-tris(diphenylphosphinomethyl)ethane (i-p₃), and its mono- and tri-sulfide, which have shorter carbon chains compared with pOp₃, form the mononuclear dichloro palladium(II) complexes with cis(P) and cis(S) geometries. Difference in the catalytic activity for the C-C coupling reaction was discussed in connection with the coordinated groups and geometries of the complexes.
