 Title    Transition Metal Complexes with Sulfur Ligands, IV [1] Synthesis and Reactions of Mo (IV) Complexes with the Tetradentate Thioether-thiol Ligand 2,3,8,9-Dibenzo-l,4,7,10-tetrathiadecane  
 Abstract    Synthesis and characterization of non-oxo Mo(IV) complexes with the tetradentate thioether-thiol ligand 2,3,8,9-dibenzo-l,4,7,10-tetrathiadecane(dttd-H2) are reported. MoCl4(THF)2 reacts with dttd-H2 in THF at room temperature to give the paramagnetic (2.61 BM, 295 K) [Mo(dttd)Cl2]. The chlorine ligands in [Mo(dttd)Cl2] can be substituted by sulfur ligands yielding diamagnetic complexes as [Mo(dttd)(CeH4S2)], [Mo(dttd)(SC2HiS)] and [Mo(dttd)(SC2H5)2]; with Na2S, NaHS or H2S, the di-^-sulfido bridged complex [(dttd)Mo(S)2Mo(dttd)] is obtained. The reduction of [Mo(dttd)Cl2] by various reducing agents in the presence of CO or NO yields labile carbonyl and nitrosyl species in solution. In contrast to [Mo(dttd)Cl2], the complexes with MoSe cbromophores showed no reactivity to CO or NO under reducing conditions.

 Title    Gehinderte Ligandbewegungen in Übergangsmetallkomplexen, XIX [1] Oktaedrische Wolfram-Olefin-Komplexe mit Bisphospbinoethan-Liganden Hindered Ligand Motions in Transition Metal Complexes, XIX [I] Octahedral Tungsten Olefin Complexes with Bisphosphinoethane Ligands  
 Abstract    (OC-6-32)-W(CO)3[(CH3)2PC2H4P(CH3)2](olefin) complexes (9-14) were prepared photochemicallyfromW(CO)4[(CH3)2PC2H4P(CH3)2](l)viaW(CO)3[(CH3)2PC2H4P(CH3)2]-(THF) (2) and the electron poor olefins dimethyl malonate(3), fumarate (4), methylfuma-rate (5), fiuorofumarate (6), chlorofumarate (7) and bromofumarate (8). The stereoche-mistry of 9-14 was elucidated by IR and NMR spectroscopy. The hindered rotations of the olefin ligands in 9-14 were studied by D-NMR spectroscopy. 11-14 form two diastereomeric isomers when the olefin rotation is freezed. The spectroscopic behaviour of the dimethyl fumarate complex 10 gives unambiguous proof for the rotation of the olefin ligand around the metal-olefin-bond. Alternative motions are ruled out.

Diiodocuprate(I) RCuI2 mit isoherten Ketten ^ [Cul4 2~] * R 1 = N-Methylpyridinium, R 2 = Dimethyl ( 3 -dimethylamino -2 -aza -2 -propenyliden ) ammonium [1] Syntheses and Structure Analyses of Iodocuprates(I): II. Diiodocuprates(I) RCUL2 with Isolated Chains [CULI/2~]; R 1 = N-Methylpyridinium, R 2 = Dimethyl(3-dimethylamino-2-aza-2-propenyliden) Ammonium  
 Abstract    N-Methylpyridinium-diiodocuprate(I), CßHgNCuI^ and dimethyl(3-dimethylamino-2-aza-2-propenyliden)ammonium-diiodocuprate(I), C6H14N3CUI2, are obtained by reacting Cu with C6H8NI3 or C6H14N3I3 in acetone. Both compounds are built up by the organic cations and chains of edge sharing tetrahedra<jo[Cul4/2-]. The iodocuprate(I) anions are in intimate contact with the cations via intermolecular I • • • C interactions. Though nearly the same average Cu-I distance of 267.2 or 268.2 pm was found for both iodocuprate(I) anions there are different Cu-Cu distances (301-354 pm).

 Title    Synthese und Struktur von C5Me5Pd(PR3)X: Palladiumkomplexe mit einem unsymmetrisch gebundenen Pentamethylcyclopentadienylring [ 1 ] Synthesis and Structure of CsMe5Pd(PR3)X: Palladium Complexes with an Unsymmetrically Bonded Pentamethylcyclopentadienyl Ring [1]  
 Abstract    The complexes C5Me5Pd(PR3)X (1-4) are prepared from [Cl(PR3)Pd]2(iM-OCOCH3)2 and TICsMes. Attempts to replace the halide ligand by a second CsMes or a C5H5 unit remained unsuccessful. The X-ray structure analysis of C5MesPd[P(i-Pr)3]Cl (3) indicates that the five-membered ring shows a tendency of »^-bonding towards the metal. Das Interesse an Pentamethylcyclopentadienyl-metall-Verbindungen ist in den letzten Jahren stän-dig gestiegen, nachdem an zahlreichen Beispielen gezeigt werden konnte, daß die Einführung des CsMes-an Stelle des CsHs-Liganden eine Zunahme der Stabilität der Ring-Metall-Bindung bewirkt [2], In der Reihe der Platinmetalle sind Komplexe mit CsMes vor allem von Rhodium und Iridium darge-stellt und auch strukturell charakterisiert worden; die Arbeiten von P. M. Maitlis und seiner Gruppe haben hier bahnbrechend gewirkt [3]. Im Vergleich dazu ist nur relativ wenig über Pentamethylcyclopentadienylpalladium-Verbindun-gen bekannt. Wir hatten kürzlich gefunden [4], daß bei der Umsetzung der Acetat-verbrückten Zwei-kernkomplexe [Cl(PR3)Pd]2(//-OCOCH3)2 mitTICsHö die Verbindungen (^ 5 -C5H5)Pd(?? 1 -C5H5)PR3 entste-hen, die in Lösung ein fluktuierendes Verhalten zei-gen. Aufgrund von !H-und 13 C-NMR-spektrosko-pischen Messungen sind zwei dynamische Prozesse nachweisbar, wobei der Prozeß mit der größeren Aktivierungsenergie ein nja-(bzw. rf/r] 1 -)-Aus-tausch der beiden unterschiedlich gebundenen Cy-clopentadienylliganden und derjenige mit der kleine-ren Altivierungsenergie eine metallotrope Umlage-rung ist.

 Abstract    Fluorapatite Ca5F(PC>4)3 can be synthesized by melting of CaF2 together with Ca3(P04)2 at 1660 °C in the molar ratio CaF2 • 3 Ca3(PÜ4)2. Fluorapatite is more resistant against acids than hydroxylapatite Cas0H(P04)3 and can activate the remineralisation in dental enamel. The apatite of dental enamel is more resistant against mechanical stress than synthetic apatite due to a different microstructure of the crystal grains.

None of these compounds was found to be more active than 1 (T/C X 100 = 339 at a dose of 65 mg/kg). Although the essential position C4 for the enzymatic activation is completely blocked in 5, the compound posses-ses a high degree of activity. This result justifies a reevaluation of the proposed mechanism of drug action of 1 and its analogs.

 Title    Synthese, Molekül-und Elektronenstruktur eines Radikal-Kationkomplexes [Cr(CO)4(Carben)2] + Synthesis, Molecular and Electronic Structure of a Radical Cationic Complex [Cr(CO)4(Carbene)2] +  
 Abstract    A new one-step synthesis for bis-carbene complexes cis-M(CO)4L2 (M = Cr, Mo, W) containing cyclic carbene ligands L has been developed. These compounds can be oxidized by ferrocenium salts to paramagnetic cation complexes [M(CO)4L2] + which, for M = Cr, are isolable in the form of their PFÖ salts. The chromium compounds with L= 1,3-dimethyl-4-imidazolin-2-ylidene permit for the first time a structural and spectroscopic comparison of a diamagnetic carbene complex with the corresponding paramagnetic cation; the experimental facts are interpreted by molecular orbital calculations.

The molecular struc-ture of 2 b was determined by X-ray diffraction analysis.

 Title    Synthese und pharmakologische Eigenschaften von silylierten Dopaminen und 4.4-Diphenylpiperidinen Synthesis and Pharmacological Properties of Silylated Dopamines and 4,4-Diphenylpiperidines  
 Abstract    Syntheses for the bis-O-trimethylsilylated (2), the tris-0,0,N-trimethylsilylated (3) and the tetrakis-0,0,N,N-trimethylsilylated dopamine (4) are described. The preparation of some N-trialkylsilylated 4,4-diphenylpiperidines 6-8 and of the N-triphenylsilylated piperidine 9 is also reported. The silylation of these neuropharmaca enhances their lipo-philic character. Preliminary pharmacological investigations show the desired central effect of these compounds. The silylated dopamines 3 and 4 influence positively the rigid akinetic syndrom, which was induced by reserpine. The silylated 4,4-diphenylpiperidines 6-9 show the same effect on the content of neurotransmitters in the rat brain as the Anti-parkinson drug l-ier£-butyl-4,4-diphenylpiperidine (budipine).

 Title    Triphenylstanny]tris(trimethylphosphan)cobalt - Molekül struktur und Eigenschaften Triphenylstannyltris(trimethylphosphane)cobalt -Molecular Structure and Properties  
 Abstract    Potassium cobaltates K+CoLsL' -(L = MeaP, L' = N2, olefin) react with SnCl(CeHs^ or GeBr(CeH5)3 to give tetracoordinate complexes containing Co-Sn and Co-Ge bonds. Crystal and molecular structures of two single crystals were determined. They show tetrahedral molecules Co[Sn(C6Hs)3][P(CH3)3]3 in different packing order. Both tetra-coordinate compounds take up small ligands thereby completing their 18-electron valence shells in compounds Co[E(C6H5)3]L3L' (L = (CH3)3P; E = Ge, L' = CO; E = Sn, L' = CO, C2H4). A sparingly soluble paramagnetic adduct Co[Sn(C6Hs)3]L4 is believed to contain a tin-bonded phosphane. Allgemeines
