摘要
Palladium(11) and nickel(II) complexes with tetradentate ligands derived from pyrrole 2-carboxaldehyde and various diamines have been synthesized and characterized. The complexes are neutral and the coordination around the metal is square-planar; they are able to activate the molecular hydrogen and to catalyse the homogenous hydrogenation of phenylacetylene. The X-ray structures of N,N'-cycloexylenebis(pyrrol-2-ylmethyleneamine) (H(2)L4), PdL4 and PdL3 (H2O, N,N'-propylenebis(pyrrol-2-ylmethyleneanime)) are discussed. (C) 2002 Elsevier Science B.V.
