Abstract

ClPd(μ-dppa)₂PdCl [dppa = bis(diphenylphosphino)aminel (1) has been prepared by treating PdCl₂(NCPh)₂ with Pd₂(dba)₃·.CHCl₃ (dba = dibenzylideneacetone) and dppa in CH₂Cl₂. Substitution reactions allow the synthesis of the neutral BrPd(μ-dppa)₂ PdBr (2) and the cationic [Ph₃PPd(μ-dppa)₂PdPPh ₃](BPh₄)₂ (4) derivatives. Complex 1 reacts with SnCl₂ yielding Cl₃SnPd(μ-dppa)₂PdSnCl₃ (3). The species R₂N⁺ and SO₂ insert into the PdPd bond of 1 to give the appropriate A-frame Pd^II-Pd^II complexes. Extrusion of SO₂ takes place at room temperature. CO does not react with 1 in CH₂Cl₂ at room temperature. The insertion-elimination reactions of 1 with isonitriles RNC (R = p-Tol Cy) have been studied. The molecular structure of ClPd(μ-dppa)₂PdCl·(CH₃)₂CO has been established by a single crystal X-ray study. The crystals are monoclinic, space group P2₁/c, with a = 13.540(3), b = 16.943(2), c = 21.082(15) Å, β = 105.257(42)° and Z = 4. The final R factor was 0.033 for 5091 observed reflections. The PdPd distance is 2.6378(6) Å.
