Synthesis and investigation of Pd(I) carbonyl complexes with heteroorganic ligands
Pd(I) carbonyl complexes are attracting attention because they have been shown to have catalytic properties in a series of organic syntheses. The stability and catalytic properties of these compounds are determined by the nature of the phosphine ligand and the bridge coordination of the carbonylgroup. Through the partial replacement of carbonyl and acido ligands by heteroorganic ligands in carbonyl halogenide and carbonyl acetate Pd(I) complexes, new stable Pd(I) complexes were obtained: (PdLX)/sub 2/CO, where L = PPh/sub 3/, X = OAc; L = AsPh/sub 3/, X = Cl, Br, OAc; L = SbPh/sub 3/, X = Cl Br, OAc; L = Ph/sub 2/PCH/sub 2/PPh/sub 2/, Ph/sub 2/AsCH/sub 2/AsPh/sub 2/, X = OAc. Atoms of the heteroorganic and acido ligands are equivalently coordinated to the palladium atoms. The carbonyl group in the complexes has bridge coordination to palladium atoms in the Pd(CO)Pd fragment; in complexes with bidentate heteroorganic ligands the covalent bond between palladium atoms is absent.
