 Abstract    IR, Raman and NMR spectroscopic studies of dimethyl(methylthio)-and dimethyl(phenyl-thio)sulfonium salts (CH 3) 2 SSR + A~ (R -CH 3 , C 6 H 5 ; A = AsF 6 ~, SbCl 6 ~) are reported. The crystal structure of (CH 3) 2 SSCH 3 + AsF 6 ~ shows for the cation a conformation different from that reported for the hexachloroantimonate.

 Title    Substitutionsreaktionen am N-[l-Chlor-2,2,2-trifluor-l-(trifluormethyl)ethyl]-dimethyIformamidin Substitution Reactions with N -[l-Chloro-2,2,2-trifluoro-l-(trifluorom ethyl)ethyl]-dim ethylform am idine  
 Abstract    It is difficult to achieve nucleophilic attack on a carbon atom bonded on two trifluoromethyl groups. However, N-[l-chloro-2,2,2-trifluoro-l-(trifluoromethyl)ethyl]-dimethylformamidine (1) reacts readily with H20 , MeOH, EtSH and P(OM e)3 even under mild conditions to form products 2, 3, 4 and 5. The reaction between 1 and Ph2PH is complex but leads in nearly quantitative yield to N-[2,2,2-trifluoro-l-(trifluoromethyl)ethyl]-dimethylformamidinium chloride 6 which has been characterized by an X-ray structure analysis. A reaction mechanism is proposed.

 Title    -Allylgermatrane. Synthesis, Structure and Reaction with Diazomethane  
 Abstract    Reaction of allyltribromogermane (2), readily available from dibrom o(l,4-dioxane)ger-manium(II) (1) and allylbromide, with tris(2-tributylstannoxyethyl)-amine (4) gives 1-allylgermatrane (3) in almost quantitative yield. 3 crystallizes from /7-pentane as a colourless crystalline solid which was characterized by 'H and ,3C NMR spectroscopy and by an X-ray crystal structure study. The "atrane" skeleton shows a strong conformational disorder; the Ge-N distance of 2.208(3) A suggests the presence of a coordinative Ge-N bond. Treatment of 1 -allylgermatrane (3) with CH2N2 in the presence of catalytic amounts of Pd(OAc)2 affords 1-cyclopropylmethylgermatrane (5) in high yield.

Reactions of 2 in TH F with electrophiles such as H 20 , D20 , Mel, Me3SiCl and Me3SnCl lead selectively to the cis-isomers 3a -6 a, whereas the analogous reactions in hexane or diethylether afford mixtures contain­ ing both cis-and rram-isomers (e.g. 3b).

NMR spectroscopic investigations of the product mixture prove the different modes of the silene cycloaddition reactions ([4+2] vs [2+2] addition). Treatment of 9 and 10 with LiA lH 4 and LiMe yield the stereo-and regioisomeric derivati­ ves (LiAlH 4: 16. 17; MeLi: 18, 19), whereas PhMgBr reacts with 10 to give only the mono substitution, the [4+2] com pound 20, and the diphenylated silacyclobutane 21. The reactions of silene 2 with pentafulvenes 6 -8 lead to similar results.

 Title    Reactivity and NMR Spectroscopic Properties of Tri(terf-butyl)plumbyl-amine  
 Abstract    Tri(rm-butyl)plumbyl-amine 1 was prepared and studied by one-(ID) and two-dimensional (2D) 'H, i3C, 5N and 207Pb NMR which allowed determination of the coupling signs /(Pb,13C) (> 0), 2y(207P b,'3C) (> 0), '7(207Pb,15N) (> 0; reduced coupling constant 1 A^(207Pb,I5N) < 0) and 27(207Pb-N-'H) (< 0). Transamination of 1 with aniline and pyrazole afforded the corresponding aniline (2) and pyrazole derivatives (3), respectively. N-Lithiation of 1, followed by treatment with Me3SiCl gave the tri(rm-butyl)plumbyl-trimethylsilyl-amine 5. The multinuclear magnetic resonance data of 2, 3 and 5 are presented. Trimethylplumbyl-phenyl-amine and trimethylplumbyl-ter/-butyl(dimethyl)silyl-amine were prepared and their NMR data were measured for comparison.

 Abstract    2-Aminophenol, salicylaldehyde and diphenylboric anhydride react in methanol to form a fluorescent, chelate-like azomethineboron compound containing methanol. The title compound, C25H20BNO2 • CH3OH, was examined by UV, IR, HI, and NMR spectroscopy as well as by thermogravimetry and X-ray structure analysis (Pbnb, a= 8.815, b= 17.309, c = 28.992 Ä, R = 5.5%). These investigations show the six-membered chelate ring (chelate A) to exist as formulated in [2] and not as a five-membered chelate ring B. One methanol molecule connects two chelate molecules by hydrogen bonds, resulting in an overall ratio of chelate to methanol of 1 : 1.

 Title    Quadrupole Effects on 73 Ge NMR Spectra in Isotopically Controlled Ge Single Crystals  
 Abstract    NMR spectra of 73 Ge (nuclear spin / = 9/2) in perfect single crystals of germanium with different isotopic content were measured at 80, 300, and 450 K. The observed specific line shapes gave evidence of the isotopic disorder, in particular, abnormal broadening of the spectrum was found for the magnetic field directed along the [111] axis. Local lattice deformations in the germanium crystal lattice due to "isotopic disorder" were calculated in the framework of the adiabatic bond charge model. The results were applied to study random non-cubic crystal field interactions with the nuclear quadrupole moments and corresponding effects on NMR spectra. The simulated second moment of the resonance frequency distributions caused by the magnetic dipole-dipole and electric quadrupole interactions are used to analyze the lineshapes, theoretical predictions being in a qualitative agreement with the experimental data.
