    Description / Table of Contents: The bis-chlorocarbonates of some oligo-ethylene glycols HO - (CH2CH2O)nH (n = 1-6) were reacted with hexamethylene diamine, m-toluylene diamine, p-phenylene diamine respectively to form the corresponding cyclic diurethanes. The dependency of the yield regarding the ringsize shows a maximum with 17 members in the ring. Also the catalyzed reaction of diisocyanates with diols was used for the preparation of cyclic urethanes.In the presence of di-n-butyltin-dilaurate exchange reactions were observed between hydroxyl-endgroups and urethane-groups as well as between urethane-groups.
    Notes: Die Bis-chlorkohlensäureester einiger Oligoäthylenglykole HO - (CH2CH2O)nH (n = 1-6) wurden mit Hexamethylendiamin, m-Toluylendiamin bzw. p-Phenylendiamin zu den entsprechenden Cyclodi-urethanen umgesetzt. Die Ausbeute in Abhängigkeit von der Ringgröße ergibt ein Maximum bei einer Ringgliederzahl von etwa 17. Ebenso wird die katalysierte Reaktion von Diisocyanaten mit Diolen zur Darstellung von Cyclo-urethanen benutzt.In Gegenwart von Di-n-butylzinndilaurat werden Austauschreaktionen sowohl zwischen Hydroxylendgruppen und Urethangruppen als auch zwischen Urethangruppen beobachtet.

    Description / Table of Contents: Chelates of 8-Quinolinol Derivatives. IV. Properties, Adduct Formation, and Extraction of Nickel(II) Chelates with n-Alkyl-8-quinolinols Containing Long Chain SubstituentsThe nickel(II) chelates of 5- and 7-nonyl-, 5- and 7-decyl- and 5-chlor-7-decyl-8-quinolinol as well as adducts with water and ammonia were synthesized and characterized by spectra and magnetic moments. The existence of associated forms was concluded. To characterize the influence of substituents the stability and composition of pyridine adducts in solution were determined. Finally the extraction of nickel(II) was studied, and a comparison of extraction data with acid and coordination stability constants was made in the case of the isomeric nonyl-8-quinolinols.
    Notes: Es wurden die Nickelchelate sowie Aquo- und Amminaddukte von 5- und 7-Nonyl-, 5- und 7-Decyl- sowie 5-Chlor-7-decylchinolin-8-ol dargestellt und spektroskopisch wie magnetochemisch untersucht. Daraus ist auf das Vorliegen assoziierter Formen zu schließen. Der Charakterisierung des Substituenteneinflusses diente die Bestimmung von Stabilität und Zusammensetzung der Pyridinaddukte in Lösung. Schließlich wurde die Extraktion von Nickel untersucht und am Beispiel der isomeren Nonylchinolin-8-ole ein Vergleich der Extraktionsdaten mit Säure- und Komplexstabilitätskonstanten vorgenommen.

    Description / Table of Contents: Several cyclic diurethanes were synthesized by two different methods applying RUGGLIZIEGLER'S principle of dilution. Only by preparation from diamines and diol-bis-chlorocarbonate good yields could be obtained. Using diols and diisocyanates as starting materials linear polyurethans were the main products.
    Notes: Mehrere Cyclodiurethane wurden unter Anwendung des RUGGLI-ZIEGLERschen Verdünnungsprinzips nach zwei verschiedenen Verfahren synthetisiert. Bei der Darstellung aus Diaminen und Diol-bis-chlorkohlensäureestern konnten die Verbindungen in guten Ausbeuten gewonnen werden. Dagegen werden bei Anwendung von Diolen und Diisocyanaten als Ausgangsmaterialien im wesentlichen lineare Polyurethane erhalten.

    Notes: The amount of adenosine triphosphate (ATP) in human lymphocytes was determined using a technique based on light emission from a bioluminescent reaction with luciferin-luciferase. The amount of ATP changed when cells were incubated in the presence of specific HLA antisera and complement. For determination of intracellular ATP a modified method was applied, which was based on reduction of extracellular ATP by the addition of ATPase. The results of titration of an anti-human lymphocyte serum using the bioluminescence assay were in agreement with the results of fluorescence vitality staining. Bioluminescent HLA-determination in 57 cell samples each tested with 5 different antisera also gave good agreement (95.8%) with the conventional method. From these experimental data the calculated ATP content per lymphocyte was 0.135 ± 0.058 pg ATP.

    Description / Table of Contents: The course of interactions betweens some aliphatic nitriles and PCI5 has been investigated by means of 31P—NMR spectroscopy. Phosphazo compounds are formed, and chlorination occurs. Three examples of cis-trans isomeric phosphazo compounds were found.
    Notes: Der Ablauf von Reaktionen einiger aliphatischer Nitrile mit PCI5 wurde mit Hilfe der 31P—KMR-Spektroskopie untersucht. In allen Fällen entstehen Phosphazoverbindungen; außerdem tritt Chlorierung ein. Drei Beispiele von cis-trans-isomeren Phosphazoverbindungen wurden gefunden.

    Description / Table of Contents: Bor-Stickstoff-Verbindungen. 94. Reaktionen von Dimethylaminoboranen mit PyrazolIn Abhängigkeit von den Reaktionsbedingungen führt die Umsetzung von Tris(dimethylamino)boran mit Pyrazol (Hpz) zu (CH3)2HNBpz3 (III) oder den Pyrazabolen B2pz4[N(CH3)2]2 (IV, cis- und trans-Isomeres), B2pz5N(CH3)2 (Va) oder B2pz6. Die Reaktion scheint über das äußerst kurzlebige [(CH3)2N]2Bpz und  -  insbesondere  -  monomeres (CH3)2NBpz2 zu verlaufen; letztere Verbindung kann massenspektroskopisch identifiziert werden. Im System Bis(dimethylamino)phenylboran-Pyrazol wurden (CH3)2HNB(C6H5)pz2 und das Pyrazabol B2pz3(C6H5)2N(CH3)2 (VII, cis- und trans-Isomeres) erhalten. Außerdem wurden einige Daten des Pyrazabols B2pz2(C6H5)2[N(CH3)2]2 erhalten, obwohl die Verbindung nicht im Reinzustand isoliert werden konnte. Die Existenz von monomerem (CH3)2NB(C6H5)pz konnte nachgewiesen werden.
    Notes: Depending on the reaction conditions, the interaction of tris(dimethylamino)borane with pyrazole (Hpz) yields (CH3)2HNBpz3 (III) or the pyrazaboles B2pz4[N(CH3)2]2 (IV, cis and trans isomer), B2pz5N(CH3)2 (Va), or B2pz6. There is evidence that the reactions proceed via the extremely short-lived [(CH3)2N]2 Bpz and, in particular, monomeric (CH3)2NBpz2; the latter species can be identified in the mass spectrometer. In the system bis(dimethylamino)phenylborane/pyrazole the species (CH3)2HNB(C6H5)pz2 and the pyrazabole B2pz3(C6H5)2N(CH3)2 (VII, cis and trans isomer) were obtained. Also, some data on the pyrazabole B2pz2(C6H5)2[N(CH3)2]2 were collected although the compound could not be isolated in the pure state. The existence of the monomer (CH3)2NB(C6H5)pz could be established.
