    Notes: The Formation of Trichlorosulfonium (IV) Hexafluoroarsenate(V)Sulfur reacts with chlorine and arsenic Trifluoride under pressure to give [SCl3]+[AsF6]-. As an intermediate oxidizing substance [AsCI4]+ is identified by spectroscopy. Depolarization-Raman-spectra confirm the assignment made in literature.

    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.

    Structure of O-Methyl-N,N-bis(trifluoromethyl)hydroxylamine, (CF3)2NOCH3 (1996)

    Topics: Chemistry and Pharmacology
    Notes: The molecular structure of (CF3)2NOCH3 was determined by gas electron diffraction. The molecular intensities were reproduced by use of a single conformation with syn orientation of the O-CH3 group relative to the nitrogen lone pair. This was confirmed by ab initio calculations (HF/3-21G(*), polarization functions only on nitrogen, and MP2/6-31G*). The observed structure demonstrates that the generalized anomeric effect is of minor importance to this compound. The following skeletal geometric parameters (bond lengths [pm] and angles [°] with 3-s̰ uncertainties) were derived: N-C 142.9(7), N-O 142(3), O-C 145(3), CNC 118.0(9), CNO 108.1(17), and NOC 109.4(17). The experimental structure is well reproduced by the ab initio calculations.

    Notes: The reaction of trimethylarsane in the superacidic systems hydrogen/fluoride antimony pentafluoride and hydrogen fluoride/arsenic pentafluoride leads to trimethylarsonium fluorometallates. These salts are stable up to 60 °C and 5 °C, respectively. Structures were successfully elucidated in the cases of trimethylarsonium undecafluorodiarsenate and trimethylarsonium hexafluoroantimonate. (CH3)3AsH+As2F11- crystallizes in the monoclinic space group P21/n with four formula units per unit cell with the dimensions a = 7.362(1), b = 12.589(1), c = 13.598(1) Å and β = 95.37(1)°. (CH3)3AsH+SbF6- crystallizes in the monoclinic space group P21/m with four formula units per unit cell with the dimensions a = 8.313(1), b = 8.855(1), c = 13.285(1) Å and β = 94.358(1)°.

Trifluoromethyldisulfane and Derivates F3CSSX (X=CF3, F, Cl, Br)The He(I) photoelectron spectra of trifluoromethyldisulfane F3CSSH and its derivatives F3CSSX (X=CF3, F, Cl, Br) are assigned by Koopmans correlations, IEnv = -εjMNDO, with MNDO eigenvalues and by radical cation state comparison. Of special interest are the nSπ/nSπ splittings, which amount to 1.15 eV F3C—SS—F or 0.87 eV in F3—SS—Cl, and the dependance of which on the dihedral angle ω(XS—SX), on the SS bond length and on the acceptor effect of the F3C substituents is discussed.

Von besonderem Interesse sind die nSπ/nSπ- Aufspaltungen, die in F3C—SS—F 1,15 eV oder in F3C—SS—Cl 0,87 eV betragen und die in Abhängigkeit vom Diederwinkel ω(XS—SX), der SS-Bindungslänge und dem Akzeptor-Effekt der F3C-Substituenten diskutiert werden.
