    Description / Table of Contents: On the knowledge of the Organo Phosphorus Compounds, XII. The Reaction of Thiophosphoryl Derivatives with Grignard Reagents and the Analysis of the Mixtures by n. m. r. Double-Resonance MethodsThe reaction of t-C4H9MgCl with (CH3)nP(S)X3-n (n = 0, 1, 2; X = Cl, Br) and of CH3MgX′ (X′ = Br, J) with (t - C4H9)nP(S)X3 - n ( 1, 2; X = Cl, Br) is investigated. The complex mixtures obtained are favourably analysed double-resonance methods as f. i. in the case of the formation of CH3(t-C4H9)P(S)J.
    Notes: Die Einwirkung von tert.-Butylmagnesiumchlorid auf (CH3)nP(S)X3-n (n = 0, 1, 2; X = Cl, Br) und die Reaktion von CH3MgX′ (X′ = Br, J) mit (t-C4H9)nP(S)X3-n (n = 1, 2; X = Cl, Br) werden untersucht. Komplexe Reaktionsgemische lassen sich vorteilhaft mittels NMR-Doppelresonanztechniken analysieren, wie u. a. am Beispiel der Bildung von (CH3(t-C4H9)-P(S)J gezeigt wird.

    Description / Table of Contents: Long range 5J(FH) and 6J(FH) couplings were observed for silanes of the type (C6F5)nSiR4-n (n = 1, 2, 3; R = alkyl, aryl) and disilanes C6F5[Si(CH3)2]2R (R = CH3, C6F5). A characteristic increase in line width for 19F-NMR spectra of (C6F5)nSiR4-n(n ≧ 2) is thought to be due to spin systems of the type ([AC]2B)n or ([AX]2M)n with intra-annular couplings between ortho-fluorine atoms of neighbouring ring systems.
    Notes: Longrange-Kopplungen des Typs 5J(FH) und 6J(FH) werden bei Silanen des Typs (C6F5)nSiR4-n (n = 1, 2, 3; R = Alkyl, Aryl) sowie den Disilanen C6F5[Si(CH3)2]2R (R = CH3, C6F5) beobachtet. Eine typische Linienverbreiterung der Fluor-resonanzspektren von (C6F5)nSiR4-n (n ≧ 2) wird auf Spinsysteme des Typs ([AC]2B)n bzw. ([AX]2M)n mit interanularen Kopplungen der ortho-Fluor-atome benachbarter Ringe zurückgeführt.

    Description / Table of Contents: The isomeric compounds 1,2-difluoro-4,5-dimethylthiobenzene and 1,4-difluoro-2,3-dimethylthiobenzene were synthesised from CH3SNa and 1,2,4,5-tetrafluorobenzene and 1,2,3,4-tetrafluorobenzene, respectively. The structures of both the C6H2F2(SCH3)2 isomers were determined by NMR spectroscopic methods. The subspectral breakdown of an [AMX3]2 spin system is shown for the limiting case of vanishing long range coupling constants.
    Notes: Aus CH3SNa und 1,2,4,5- bzw. 1,2,3,4-Tetrafluorobenzol wurden 1,2-Difluor-4,5-dimethylthiobenzol bzw. 1,4-Difluor-2,3-dimethylthiobenzol dargestellt. Die Struktur der beiden C6H2F2(SCH3)2-Isomeren wurde durch kernresonanz-spektroskopische Methoden bestimmt. Der subspektrale breakdown des [AMX3]2-Spinsystems wird für den Sonderfall verschwindender long-range-Kopplungen abgeleitet.

Dynamisch gemittelte und ionenspezifische Chemische Verschiebungen δP werden abgeleitet.
    Notes: The title compounds are prepared via Gabriel-synthesis following known or improved procedures. Novel methods using 31P{1H}-NMR controlled titrations of aminomethylphosphine oxides lead to dissociation constants (given as basicity or acidity constants resp.) and to stability constants. Dynamically averaged and ion specific chemical shifts δP were derived.
