    Description / Table of Contents: Novel Inorganic Ring Systems. XX. Tricyclic Inorganic Ring Systems with Four and Five Different ElementsThe four ring systems D, E, F and G unknown solong, could be synthesized according to Schema 1. Their structure was confirmed by mass, proton resonance, and infrared spectroscopy. The single compounds are characterized by a deep green colour and an unusually high solubility in indifferent organic solvents.
    Notes: Die vier bisher unbekannten Ringsysteme D, E, F und G konnten nach den Angaben des Schema 1 synthetisiert werden. Ihre Struktur wurde durch Massen-, NMR- und IR-Spektren sowie Röntgenstrukturanalysen sichergestellt. Die einzelnen Verbindungen zeichnen sich durch eine tiefgrüne Farbe und ungewöhnlich hohe Löslichkeit in inerten organischen Lösungsmitteln aus.

    Description / Table of Contents: Chemistry of Silicon-Nitrogen Compounds. CXXXI. 1,2-Bis (organylamino) - tetramethyldisilaries and their Transformation into N,N′-Bis (organyl) octamethyltetrasiladiaza-cyclohexanes1,2-Bis(organylamino)disilanes A 1-4 were prepared via equ. 3 by aminolysis of 1,2-dichlorotetramethyldisilane and transformed by three different methods (equ. 7; 8/9 and 10/11) into the N,N′ variied tetrasiladiazacyclohexanes B 2-5. Physical, analytical and structural information can be taken from tables 1-3. The bond increments (N)Si—Si(N) of the EISENLOHR molar refractions MRE were reinvestigated with 24.5 instead of 30.0.

    Description / Table of Contents: Chemistry of Silicon-Nitrogen Compounds. CXXXII. Derivatives of the 1,2,4-Trisila-3,5-diaza-cyclopentane Ring SystemThe derivatives B1-B6 of the title ring system could be prepared for the first time by reaction of 1,2-bis(alkylamino)disilanes (A1, A2) with dihalosilanes (Scheme 1).

    Description / Table of Contents: Novel Inorganic Ring Systems. XXII. Novel Spirosilazanes of the Si5N4, Si5N5, Si5N4O, and Si7N8 SkeletonWe succeeded in preparing the four novel spirosilazane skeletons E, F, G, and H of the composition given in the title. The permethylated compounds of the mentioned systems have been characterized in their chemical and physical properties. The conformation of their structure was possible by elemental analysis and by n.m.r., mass, i.r., and Raman spectra.

    Description / Table of Contents: Novel Inorganic Ring Systems. 28. The Spiro[4,3]-tetrasilatetrazaoctane SystemAccording to scheme 3 the spiro[4,3]-tetrasilatetrazaoctanes B are formed with high yields. Their properties are described. Physical and analytical data as well as some results for the proof of structure can be taken from tables 1—3. The very easy proceeding hydrolysis of B2 leads to A8 (scheme 4). On the contrary hydrolysis of A1 is difficult to realize and results in A3 as the main product (scheme 2).
    Notes: Nach Schema 3 bilden sich mit hohen Ausbeuten die Spiro[4,3]-tetrasilatetrazaoktane B1-5. Ihre Eigenschaften werden beschrieben. Physikalische, elementar- und strukturanalytische Daten sind in den Tab. 1-3 niedergelegt. Die sehr leicht ablaufende Hydrolyse von B2 führt zu A8 (Schema 4), die nur sehr schwer zu realisierende von A1 ergibt als Hauptprodukt A3 (Schema 2).
