    Tetra o-Tolyltin and its Halogen Derivatives (1966)

    Beschreibung / Inhaltsverzeichnis: Tetra-o-tolylzinn wurde in 45proz. Ausbeute mit Hilfe der Wurtz-Reaktion (Petroläther als Lösungsmittel; Hg als Katalysator) dargestellt. Durch Jodierung wurden daraus Tri-o-tolylzinnjodid und Di-o-tolylzinndijodid erhalten; ferner gelang die Darstellung von Tri-o-tolylzinnfluorid.
    Notizen: Tetra-o-tolyltin has been prepared in 45% yield for the first time by Wurtz reaction. Optimum yield is obtained using pet-ether (b. p. 65-85) as solvent and small amounts of mercury as catalyst. A mechanism for the role of mercury in the reaction is suggested. Tri-o-tolyltin iodide and hitherto unknown di o-tolyltin di-iodide have been prepared in 65% and 55% yields respectively by controlled iodination of the compound. Tri o-tolyltin fluoride has also been synthesised for the first time in almost quantitative yield.

    Morphology of a liquid-crystalline polyester film (1988)
    Bognor Regis [u.a.] : Wiley-Blackwell

    Notizen: Morphological studies are reported for a thermotropic liquid crystalline polyester. Small angle light scattering studies were carried out as a function of temperature using Hv and Vv polarization with photographic as well as photometric techniques. No scattering was observed from a thin film cast from a dilute solution of the polymer in a highly volatile solvent. When the film was heated, scattering of light was observed above the glass transition temperature of the polyester. The scattering was found to be azimuthally dependent with Vv intensities being much higher than the corresponding Hv intensities. The size of the morphological features responsible for SALS patterns were calculated and were found not to change significantly with temperature ranging from glass transition temperature to the solid-nematic transition temperature of the polyester. The WAXS pattern of solution cast polymer was representative of an amorphous structure. Solution cast films heat treated under various conditions (all above the Tg of the polymer) contained crystalline as well as amorphous structures. The maximum apparent crystallinity for annealed samples was of the order of 30%.

    Structural Studies on Indium and Tin Thiobenzoates (1996)

    Notizen: Indium(III) and tin(IV) thiocarboxylates were prepared and characterized on the basis of their IR, 13C- and 19Sn-NMR data. Indium tris(thiobenzoate) (1) decomposes into a sulfido complex In (S)[S(O)CPh] (2a). The corresponding tris(thioacetate) In[S(O)CMe]3 is thermally too unstable to be isolated. The anionic tetrakis complex [Et3NH]{In[S(O)CPh]4} (3) was characterized by X-ray crystallography which revealed a distorted tetrahedral coordination at the In atom. X-ray diffraction analysis of the complexes BuSn[S(O)CPh]3 (4) and Cl2Sn[S(O)CPh]2 (7) showed distorted tetrahedral and cis-octahedral structures, respectively.

    Polymerization of acrylamide initiated by the Ce4+/thiourea redox system (1982)
    New York : Wiley-Blackwell
    Journal of Polymer Science: Polymer Chemistry Edition 20 (1982), S. 131-136 
    Details
    ISSN: 0360-6376

    Thema: Chemie und Pharmazie
    Notizen: The polymerization of acrylamide (M) initiated by the Ce4+/thiourea (TU) redox system has been studied in an aqueous sulfuric acid medium at 35 ± 0.2°C under nitrogen atmosphere. The rate of polymerization is governed by the expression \documentclass{article}\pagestyle{empty}\begin{document}$$R_p = K_p [{\rm M}]^{1.20} [{\rm Ce}^{{\rm 4 +}}]^{0.5} [{\rm TU}]^{0.5}$$\end{document} The activation energy is 5.9 kcal deg-1 mol-1 in the investigated temperature range 30-50°C. The molecular weight is directly proportional to the concentration of monomer and inversely proportional to the catalyst concentration. With increasing concentration of DMF molecular weight decreases. The range of concentrations for which these observations hold at sulfuric acid concentration of 2.5 × 10-2 mol/L are [monomer] = 5.0 × 10-2-3.0 × 10-1, [catalyst] = (5.0-15.0) × 10-4, and [activator] = (1.0-6.0) × 10-3 mol/L.
