    Description / Table of Contents: Dimethylboron azide can be prepared from dimethylboron bromide and tri-n-butylsilyl azide as an explosive liquid, b. p. 54°C/720 mm. A temperature-dependent association equilibrium is found for the substance by 1H- and 11B - NMR spectroscopy. The IR vibrations in the range 33-4000 cm-1 are consistent with a Cs-type structure. Some amino complexes of dimethylboron azide are described. On heating the pyridine complex up to 210-220°C, more than 30 compounds are formed the most important of which is hexamethyl borazine, which is found in a yield of 21%.
    Notes: Dimethylborazid entsteht aus Dimethylborbromid und Tri-n-butylsilylazid als explosive Flüssigkeit, Sdp. 54°C/720 Torr. Aus den 1H- und 11B - NMR-Signalen der Substanz geht hervor, daß sie einem temperaturabhängigen Assoziationsgleichgewicht unterliegt. Die im Bereich 33-4000 cm-1 gemessenen IR-Banden lassen sich einem Strukturmodell der Punktgruppe Cs zuordnen. Einige Aminate von Dimethylborazid werden beschrieben. Beim Zerfall von Dimethylborazid-Pyridin bei 210-220°C entstehen mehr als 30 Verbindungen, darunter in 21proz. Ausbeute als Hauptprodukt Hexamethylborazol.
