Mechanismus der Reduktion von Tosylhydrazonen mit komplexen Metallhydriden
Authors: Fischer Martin , Pelah Zvi , Williams Dudley H. , Djerassi Carl 
Published: June 2007

AbstractDurch Reduktion von Tosylhydrazonen mit LiAlD4 oder NaBD4 lassen sich monodeuterierte Kohlenwasserstoffe herstellen. Mechanismus und stereochemischer Verlauf der Tosylhydrazonreduktion werden mit Hilfe von deuterierten Reagenzien aufgeklärt. Außerdem wird die Abhängigkeit der konkurrierenden Olefinbildung von α‐ständigen Substituenten und von den Reaktionsbedingungen untersucht.
Die Kernresonanzspektren von Steroiden in polaren Lösungsmitteln. 1. Dimethylsulfoxid (DMS)
Authors: Hampel Bruno , Krämer Josef M. 
Published: June 2007

AbstractBei 70 Steroiden, vorwiegend aus dem Corticoid‐Gebiet, ist die Lage der NMR‐Signale in Dimethylsulfoxid‐d6 derjenigen in CDCl3 sehr ähnlich. Die bekannten Regeln können daher mit entsprechender Vorsicht auch in DMS‐d6 angewandt werden. Ausnahmen betreffen die Dipolwirkungen funktioneller Gruppen.
Cyansäureester, V. Acylierungs‐ und Phosphorylierungsreaktionen mit Cyansäureestern als dehydratisierende Agentien
Authors: Martin Dieter 
Published: June 2007

AbstractDie Primäraddukte von Säuren an Cyansäureester (1) sind starke Acylierungsmittel. Carbon‐, Thiocarbon‐, Sulfon‐ und Phosphorsäuren werden mit 1 in ihre Anhydride übergeführt und in alkoholischer Lösung verestert. Der Veresterungsgrad der Orthophosphorsäure läßt sich durch die Menge der zugesetzten Base selektiv zur Mono‐ oder Diesterstufe lenken. Mit Toluolsulfonsäureester, Alkohol und 1 entstehen Orthokohlensäureester. Amidierungen können mit 1 nur bei Thiocarbon‐ und Monoesterphosphorsäuren erreicht werden. Dithiocarbamidsaure Ammoniumsalze bilden mit 1 je nach der Art des Kations wahlweise Thioharnstoffe oder Senföle. Carbonsäureamide und Oxime lassen sich mit 1 zu Nitrilen und N‐Nitroso‐N‐phenyl‐glycin zu Phenylsydnon dehydratisieren.

Published: June 2007

AbstractBei der Einwirkung von Natriumacetylid in flüssigem Ammoniak auf Thiobenzophenon entsteht Bis‐benzhydrylmercapto‐äthin (4) neben Tetraphenyläthylen. Die unterschiedliche Reaktionsweise von Carbonyl‐ und Thiocarbonylgruppen wird diskutiert und eine unabhängige Synthese für 4 beschrieben.
Die Konstitution von Vitamin B12s
Authors: Schrauzer Gerhard N. , Windgassen Richard J. , Kohnle Josef 
Published: June 2007

AbstractAus Versuchen mit Vitamin B12s und reduzierten Bis‐dimethylglyoximkobalt‐Komplexen („Cobaloxims”︁) wird gezeigt, daß Vitamin B12s und Cobaloxims anionische Komplexe des +I‐wertigen Kobalts sind, die mit den korrespondierenden freien Säuren im Hydrolysegleichgewicht stehen: magnified image Aus pH‐Messungen wird der pKs‐Wert der freien Säure für ein spezielles Cobaloxims zu 10.54 bestimmt; die Säuren selbst sind im freien Zustand unbeständig und zerfallen unter Wasserstoffentwicklung. Die charakteristische Farbe der Cobaloximes und des Vitamin B12s wird im wesentlichen durch Ligandenfeldübergänge im sichtbaren Spektralbereich verursacht, deren Lage von der Natur der noch an das Kobalt gebundenen Basenkomponente abhängt. Die hohe nucleophile Reaktivität des Kobalts in diesen Komplexen und der Mechanismus der Reaktionen mit organischen Substraten wird erklärt.

Vapour growth and morphology of PbBr2 crystals
Authors: Kaito Takamasa , Yanagiya Shin‐Ichiro , Mori Atsushi , Inoue Tetsuo 
Published: June 2007

AbstractIn this paper, the vapour transport of PbBr2 under vacuum during vacuum distillation refining and its condensation on the wall of the vessel were described. The macro‐ and micro morphologies of PbBr2 crystals grown in the vessel (glass tube) were studied. The crystal shape changed dramatically depending on the positions of condensation in the vessel, i.e., the crystal shape varied from an isometric polyhedron to columnar crystals with facets, and to a massive crystal without facets with a rise in the wall temperature. These results were interpreted in terms of the concentration gradient of the molecules in the vessel, surface roughening and/or surface melting of the crystals. (© 2007 WILEY‐VCH Verlag GmbH & Co.

Growth and crystal structure of the layered compound TlGaSe2
Authors: Delgado G. E. , Mora A. J. , Pérez F. V. , González J. 
Published: June 2007

AbstractThe semiconducting compound TlGaSe2 was grown by solid state reaction technique. The crystal structure of this material was confirmed by single‐crystal X‐ray diffraction. TlGaSe2 crystallizes in the monoclinic system with space group C2/c (No. 15), Z = 16 and unit cell parameters a = 10.779(2) Å, b = 10.776(1) Å, c = 15.663(5) Å, β = 99.993(6)°. The structural refinement converged to R(F) = 0.0719, R(F2) = 0.0652 and S = 1.17. The structure consists of a three‐dimensional arrangement of distorted TlSe8 and GaSe4 polyhedrons.

Growth of calcium oxalate crystals induced by complex films containing biomolecules
Authors: Xie Anjian , Shen Yuhua , Ma Dong , Huang Fangzhi , Qiu Lingguang , Li Shikuo , Chen Long 
Published: June 2007

AbstractNucleation and growth of calcium oxalate (CaC2O4) crystals induced by films composed of phosphatidylcholine (PC), cholesterol (CS) and human serum albumin (HSA), and of PC, CS and dextran have been carried out. The products obtained were characterized by Fourier transform infrared spectroscopy, scanning electron microscopy and ultraviolet‐visible spectroscopy. The results indicate that hexagonal calcium oxalate monohydrate (COM) and club‐shaped calcium oxalate trihydrate (COT) crystals are obtained on the PC/CH/HSA film, and the microstructure and properties of the PC/CH/HSA film depend on the weight ratio of PC to CS. With an increase in the PC‐to‐CS ratio, the number of COM crystals decreases gradually, and finally disappear, suggesting that PC inhibits the growth of COM crystals. On the PC/CS/dextran film, irregular COM and COT crystals are formed. The possible formation mechanisms of CaC2O4 on the two complex films are discussed. (© 2007 WILEY‐VCH Verlag GmbH & Co.

Some peculiarities of Ti in‐diffusion in lithium niobate
Authors: Tsirlin M. , Dariel M. 
Published: June 2007

AbstractThe process of one‐ and two‐dimensional Ti in‐diffusion in lithium niobate, LiNbO3 (LN), single crystals of 〈x〉 and 〈z〉 orientations at 950‐1060°C in oxygen/water vapor medium had been studied. In the case of one‐dimensional diffusion, a flat diffusion front consisting of Ti solid solution in LN is formed. The process kinetics is described by Fick's equation for the case of a permanent source. In the case of two‐dimensional Ti diffusion, the diffusion zone contour acquires the shape close to elliptical. The diffusion rate in the tangential direction is about an order of magnitude higher than in the normal direction. A model qualitatively describing such nontrivial character of the diffusion process is suggested. The model is based on: a) incongruent lithium evaporation out of LN at high temperatures; b) low thermodynamic activity of Li in LiTiO3 – product of Ti interaction with LN. These factors produce a significant nonlinearity of the process, since a strong chemical bond between Li and Ti in this phase leads to a mutual increase in their diffusive mobility.
