    Description / Table of Contents: Metal Complexes with Biologically Important Ligands, XXXIV. Allyl-Palladium(II) and Triphenylphosphane Gold(I) Complexes with Nucleobases and NucleosidesThe reactions of (η3-allyl)Pd(μ-Cl)2Pd(η3-allyl) (A) and (COD)Rh(μ-Cl)2Rh(COD) with nucleobases and nucleosides give the complexes (η3-C3H5)Pd(L)Cl (1) (L = inosine, adenosine, guanosine, cytosine, cytidine, 2-thiouracil, 2-thiocytosine) and (COD)Rh(cytosine)Cl (2), respectively. With adenosine and purine also ligand bridged complexes (η3-C3H5)(Cl)Pd—L—Pd(Cl)(η3-C3H5) (3) have been obtained. Ph3PAuCl reacts with the anions L′ of purine, adenine, uridine, and inosine to give the complexes Ph3PAuL′ (5). Ph3PAu+ is added to both N atoms of the dianion of uracil with formation of 6. The coordination of the nucleobases is discussed on the basis of the 1H and 13C NMR spectra. The X-ray structure of Ph3PAu(adeninate) (5b) has been determined.
    Notes: Die Umsetzung von (η3-Allyl)Pd(μ-Cl)2Pd(η3-Allyl) (A) sowie von (COD)Rh(μ-Cl)2Rh(COD) mit Nucleobasen und Nucleosiden liefert unter Spaltung der Chlorobrücken die Komplexe (η3C3H5)-Pd(L)Cl (1) (L = Inosin, Adenosin, Guanosin, Cytosin, Cytidin, 2-Thiouracil, 2-Thiocytosin) bzw. (COD)Rh(Cytosin)Cl (2). Mit Adenosin und Purin wurden auch Ligand-verbrückte Komplexe (η3-C3H5)(Cl)Pd—L—Pd(Cl)(η3-C3H5) (3) erhalten. Ph3PAuCl setzt sich mit den Anionen L′ von Purin, Adenin, Uridin und Inosin zu Ph3PAuL′ (5) um; Ph3PAu+ addiert sich an die beiden N-Atome des Dianions von Uracil unter Bildung von 6. Die Koordination der Nucleobasen wird anhand der 1H- und 13C-NMR-Spektren diskutiert. Die Struktur von Ph3PAu (Adeninat) (5b) wurde röntgenographisch bestimmt.
