    Description / Table of Contents: Contributions to the Chemistry of Sulfur Halides. 8. Trifluoromethylbromosulfan - Gas Phase Structure and Normal Coordinate AnalysisAn improved method to prepare CF3SBr is reported. An electron-diffraction measurement has been carried out and the following molecular parameter are obtained (rα° values in Å and degree): C—F = 1.331(3), C—S = 1.814(6), S—Br = 2.162(6), CSBr = 99.4(3), FCF = 108.7(9), Tilt = 5.5(5).A reassignment of the vibrational frequencies based on IR-matrix and Raman measurements is given and the valence force constants of CF3SBr are calculated.
    Notes: Es wird über ein verbessertes Verfahren zur Darstellung von CF3SB1 und die Bestimmung der Molekülstruktur durch Elektronenbeugung berichtet. Folgende Parameter werden erhalten (rα°-Werte in Å und Grad): C—F = 1,331(3), C—S = 1,814(6), S—Br = 2,162(6), CSBr = 99,4(3), FCF = 108,7(9), Tilt = 5,5(5).Auf Grund von IR-Matrix- und Raman-Messungen erfolgt eine Neuzuordnung der Schwingungsfrequenzen, die durch eine Normalkoordinatenanalyse unterstützt wird.

    Description / Table of Contents: Contribution to the Chemistry of Sulfur Halides. 11. UV/VIS Spectroscopic Investigations on the Existence of CF3S(O)I and the Vibrational Spectrum of CF3S(O)BrThe very instable compound CF3S(O)I is identified by correlating its UV/VIS absorptions (245, 310, 340 nm) with those of the homologous trifluoromethylsulfinylhalides and by the decomposition products. The assigned vibrational spectrum of CF3S(O)Br is given.
    Notes: Sehr instabiles CF3S(O)I wird durch Vergleich seiner UV/VIS-Absorptionen bei 245, 310, 340 nm innerhalb der Reihe der Trifluormethylsulfinylhalogenide und durch seine Zerfallsprodukte identifiziert. Es wird die Zuordnung der Schwingungen von CF3S(O)Br angegeben.

    Description / Table of Contents: Formation Structure and Reactions of Methyl(methylimino)-boraneThe iminoborane MeB≡NMe is formed by gas-phase thermolysis of the aminoborane Me2BN(SiMe3)OSiMe3 or the azidoborane Me2BN3. The NMR shifts at -80°C, the IR spectrum in Armatrix, and the PE spectrum correspond to a molecular structure comparable to that of 2-butyne, MeC≡CMe. The title compound is thermally stabilized by cyclotrimerisation, it is butyloborated at the BN bond by tributylborane, and it adds benzyl azide by a [2 +3] cycloaddition.
    Notes: Das Iminoboran MeB≡NMe entsteht bei der Gasphasenthermolyse des Aminoborans Me2BN(SiMe3)OSiMe3 oder des Azidoborans Me2BN3. Die Kernresonanzverschiebungen bei -80°C, das Infrarotspektrum in Argonmatrix und das Photoelektronenspektrum sprechen für einen Molekülbau, der dem von 2-Butin, MeC≡CMe, ähnlich ist. Die Titelverbindung stabilisiert sich thermisch durch Cyclotrimerisierung. Von Tributylboran wird sie an der BN-Bindung butyloboriert, und mit Benzylazid geht sie eine [2 + 3]-Cycloaddition ein.
