    Description / Table of Contents: Investigations on Diazo Compounds and Azides, XXV1) Azide Additions on (Silylethynyl)-, (Germylethynyl)- and (Stannylethynyl)aminesThe lithium acetylides 1 react with trialkyl- and triphenylmetal halides 2 to form the (silylethynyl)-, (germylethynyl)-, and (stannylethynyl)amines 3. The ynamines add aryl-and sulfonyl azides to the 5-amino-1, 2,3-triazoles 4,5, and 7, which in the case of the sulfonyl azide adducts 5 and 7 isomerize largely to the diazoacetamidines 6 and 8, respectively. Water or deuterium oxide hydrolyze the carbon-metal bond of the diazo compounds 8 with formation of the [2-H1] - and [2-D1]diazoacetamidines 9 and 10.
    Notes: Durch Umsetzung von Lithiumacetyliden 1 mit Trialkyl- und Triphenylmetallhalogeniden 2 werden (Silyläthinyl)-, (Germyläthinyl)- und (Stannyläthinyl)amine 3 synthetisiert. Diese Inamine addieren Aryl- und Sulfonylazide zu den 5-Amino-1,2,3-triazolen 4,5 und 7, die im Falle der Sulfonyladdukte (5 und 7)weitgehend zu den Diazoacetamidinen 6 bzw. 8 isomerisieren. Die Diazoverbindungen 8 spalten den Metallrest bei Einwirkung von Wasser oder Deuteriumoxid leicht ab unter Bildung der [2-H1]- und der [2-D1]Diazoacetamidine 9 und 10.

    Description / Table of Contents: Investigations on Diazo Compounds and Azides, XXIX: Oxygen Shift in Sulfonyl Azide Additions to (Ethyl- and Phenylthioethynyl)aminesThe (ethyl- and phenylthioethynyl)amines 5a-d add 4-nitrophenyl azide to form the 1,2,3-triazoles 6a-d. In contrast to this result the reaction of sulfonyl azides with the same alkynes leads to nitrogen evolution and oxygen shift with formation of S-ethyl (and phenyl) amidinothioformates 9a-h. The reaction mechanism is discussed.
    Notes: Die (Ethyl- und Phenylthioethinyl)amine 5a-d addieren 4-Nitrophenylazid zu den 1,2,3-Triazolen 6a-d. Im Gegensatz dazu reagieren Sulfonylazide mit den gleichen Alkinen unter Stickstoffabspaltung und Sauerstoffverschiebung zu den Thiooxalamidin-S-ethyl(und phenyl)estern 9a-h. Der Reaktionsablauf wird diskutiert.
