    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: 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.

    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: Ammonolysis Reaction of (NH4)2GeF6. Synthesis and Structure of NH4[Ge(NH3)F5](NH4)2GeF6 reacts with ammonia to yield NH4[Ge(NH3)F5] at 280°C. The reaction path was elucidated by in situ time and temperature resolved X-ray powder diffraction. NH4[Ge(NH3)F5] crystallizes isostructurally to NH4[Si(NH3)F5] in the tetragonal space group P4/n (No. 85) with lattice constants a = 619.41(1) pm and c = 724.70(1) pm. The germanium atom is coordinated by five fluorine atoms and the nitrogen atom of the ammonia molecule. The ammonium cation is located on the Wyckoff position (2 a) in P4/n. The crystal structure is stabilized by extensive hydrogen bonding.
    Notes: (NH4)2GeF6 reagiert mit Ammoniak bei 280°C zu NH4[Ge(NH3)F5]. Der Reaktionsverlauf wurde in situ mit Hilfe der zeit- und temperaturaufgelösten Röntgenpulverdiffraktometrie verfolgt. Das so dargestellte NH4[Ge(NH3)F5] kristallisiert isostrukturell mit NH4[Si(NH3)F5] in der tetragonalen Raumgruppe P4/n (Nr. 85) mit den Gitterkonstanten a = 619,41(1) pm und c = 724,70(1) pm. Dabei ist das Germaniumatom verzerrt oktaedrisch von fünf Fluoratomen und dem Stickstoffatom des Ammoniakmoleküls koordiniert. Das Ammoniumion liegt auf der Tetraederpunktlage (2 a) in P4/n. Die Verbindung wird durch Wasserstoffbrückenbindungen stabilisiert.
