    Description / Table of Contents: Crystal Structure of BaHg(CN)4 · 4 PyridineThe structure of the tetragonal BaHg(CN)4 · 4 Pyridine (space group I4, a = 1119.4(7), c = 1 057.9(7) pm, Z = 2, dc = 1.87 g · cm-3) contains tetrahedral Hg(CN)4 and bisdisphenoide Ba(NC)4(py)4 groups, which are linked together by Hg—CN—Ba bridges. The BaHg(CN)4 framework consists of a 3-dimensional network of all round edge-sharing tetrahedrons. The analogous strontium compound is isotype with a = 1 108.2(9) and c = 1 035.3(14) pm.

    Description / Table of Contents: Antitumor Active cis-Platinum(II) Complexes with α-Amino Acid Esters and Peptide Esters. X-Ray Structure of cis-Dichlorobis(glycylglycine ethyl ester)platinum(II)A series of cis-platinum(II) complexes X2PtL2 (1-4) (X = halide, 2X = oxalate, malonate; L = α-amino acid ester, peptide ester) has been obtained from Pt42- and L. The dipeptide ester complexes are also accessible via peptide synthesis at the complex from Cl2Pt(NH2CHRCO2H)2 and α-amino acid esters using carbodiimide as coupling agent and the platinum atom as amino protecting group. The complexes Cl2PtL2 with α-amino acid ester ligands have also been prepared from the bis(chelate) compounds cis-Pt(NH2CHRCO2)2 and alcohol in the presence of HCl. The complexes have been characterized by their spectroscopic data, cis-Cl2Pt(GlyGlyOEt)2 (2a) by an X-ray analysis.
    Notes: Eine Reihe von cis-Platin(II)-Komplexen X2PtL2(1-4) (X = Halogenid, 2X = Oxalat, Malonat; L = α-Aminosäureester, Peptidester) wird aus PtX42- und L erhalten. Entsprechende Komplexe mit Dipeptidester-Liganden sind auch durch Peptidsynthese am Komplex aus Cl2Pt-(NH2CHRCO2H)2 und α-Aminosäureestern mit Carbodiimid als Kupplungskomponente und Platin als Aminoschutzgruppe zugänglich. Die Verbindungen Cl2PtL2 mit α-Aminosäureester-Liganden lassen sich auch aus den Bis(chelat)-Komplexen cis-Pt(NH2CHRCO2)2 und Alkohol in Gegenwart von HCl gewinnen. Die cis-Struktur der Verbindungen wurde spektroskopisch, die von Cl2Pt(GlyGlyOEt)2 (2a) durch Röntgenstrukturanalyse nachgewiesen.

    Description / Table of Contents: Reactions of Glycinato Compounds of Platinum(II), Palladium(II), and Copper(II) with Amide Acetals: Schiff Base ComplexesA series of Schiff base complexes of platinum(II), palladium(II), and copper(II) 1-4 has been obtained from glycinato chelate compounds and amide acetals. The structure of the complexes has been determined by their IR and NMR spectra, that of 3a by an X ray structure analysis. With trans-bis(glycinato)platinum(II) also reaction with DMF at the α-methylene group of a glycinate ligand has been observed to give a serine derivative as ligand (5), the Schiff base complex 2a being isolated as intermediate. The first step of these reactions always is an attack of the amide acetal at the amino group; the coordinated and activated Schiff base ligands may also react at the α-methylene group.
    Notes: Eine Reihe von Schiffbase-Komplexen von Platin(II), Palladium(II) und Kupfer(II) 1-4 wird aus Glycinato-Chelatkomplexen und Amidacetalen erhalten. Die Struktur der Verbindungen wird spektroskopisch, die von (3a) durch Röntgenstrukturanalyse bestimmt. Bei trans-Bis(glycinato)platin(II) wird mit DMF auch Reaktion an der α-Methylengruppe eines Glycinat-Linganden unter Bildung eines Serinderivats als Liganden (5) beobachtet, wobei der Bis(Schiffbase)-Komplex 2a als Zwischenprodukt isoliert werden kann. Amidacetale greifen (Glycinato)platin(II)-Komplexe primär stets an der Aminogruppe an, erst im zweiten Schritt kann die Reaktion an der α-Methylengruppe des koordinierten Schiffbase-Liganden erfolgen.

    Description / Table of Contents: 7-Thiatetracyclo[4.1.0.02,4.03,5]heptane (Benzvalene Sulfide)  -  Synthesis and ReactionsThe reaction of benzvalene (1) with N-(chlorothio)succinimide gives a mixture of the 1:1-adducts 5 and 6, the treatment of which with lithium aluminium hydride transforms 5 into 7-thiatetracyclo[4.1.0.02,4.03,5]heptane (4). Among the electrophiles studied only acids attack the bicyclo[1.1.0]butane portion of 4 and produce 3-thia-trans-tricyclo[4.1.0.02,4]heptanes (9) functionalized in exo-5-position. Peracids transfer an oxygen atom to the sulfur atom of 4 to give the episulfoxide 7. Bromine and chlorine transform 4, probably via the sulfenyl halide intermediates 10, into the bis(trans-3-halotricyclo[3.1.0.02,6]hex-4-yl) disulfides 11 and 12. Mixtures of the disulfides 15 and 16 and the sulfides 19 and 20 are obtained from 4 and thiophenol under the conditions of a radical reaction. Most likely the attack of a phenylthiyl radical at the sulfur atom of 4 initiates the complex reaction sequence.
    Notes: Die Umsetzung von Benzvalen (1) mit N-(Chlorthio)succinimid erbringt ein Gemisch der 1:1-Addukte 5 und 6, bei dessen Behandlung mit Lithiumaluminiumhydrid 5 in 7-Thiatetracyclo[4.1.0.02,4.03,5]heptan (4) übergeht. Als einzige der untersuchten Elektrophile greifen Säuren das Bicyclo[1.1.0]butan-System von 4 an und bringen so exo-5-funktionalisierte 3-Thia-trans-tricyclo[4.1.0.02,4]heptane (9) hervor. Persäuren übertragen auf das S-Atom von 4 ein Sauerstoff-atom unter Bildung des Episulfoxids 7. Brom und Chlor wandeln 4 wohl über die Sulfenylhalogenid-Zwischenstufen 10 in die Bis(trans-3-halogentricyclo[3.1.0.02,6]hex-4-yl)disulfide 11 und 12 um. Unter den Bedingungen einer Radikalreaktion entstehen aus 4 und Thiophenol Gemische der Disulfide 15 und 16 und der Sulfide 19 und 20. Wahrscheinlich löst die Addition eines Phenylthiylradikals an das S-Atom von 4 das komplexe Geschehen aus.
