    Description / Table of Contents: Synthesis of Covalent Nitrogen compounds with Di-and Tetravalent TinDi-tert-butylbis(tert-butyllithioamino)stannane (2) reacts with tin (II) chloride to form the fourmembered ring 3, the first cyclodistannazane containing di-and tetravalent tin. The corresponding reaction of 2 with dichloromethane gives no carbocyclic compound 4 but the secondary bis(alkylamino) stannane 1 and polymers. The ammonolysis of the chloro(silylamino)stannane 6 yields as main products the cyclotristannazane 5 and the N, N′-disilylated secondary diaminostannane 7 besides different silicon-nitrogen compounds.
    Notes: Di-tert-butylbis(tert-butyllithioaminostannan) (2) reagiert mit Zinn (II)-chlorid zum Vierring 3, dem ersten Cyclodistannazan mit zwei-und vierwertigem Zinn. Die entsprechende Umsetzung von 2 mit Dichlormethan führt überraschend nicht zum Carbocyclus 4 sondern zur Bildung des sekundären Bis(alkylamino)stannans 1 und polymeren Stoffgemischen. Bei der Ammonolyse des Chlor-(silylamino)stannans6 erhält man neben verschiedenen Silicium-Stickstoffverbindungen haupt-sächlich das Cyclotristannazan 5 sowie das N, N′-disilylierte sekundäre Diaminostannan 7.
