    Description / Table of Contents: Trimethylstannyl- and Dimethylstannyl-substituted Pyrroles - Synthesis, Spectra, and StructuresMonomeric trimethylstannyl pyrroles, Me3Sn—R (Me = CH3 and R = —NC4H4, —NC4H2Me2-2,5, —NC4Me4-2,3,4,5, —C4H3NMe-1), are synthesized by metathesis reactions from Me3SnCl with 1(N)- and 2(C)-lithium pyrroles, respectively. An almost similar procedure gives monomeric dimethylstannylbis(pyrroles), Me2SnR2 (1 a - 3 a), from Me2SnCl2 and 1-Li-pyrrolides (1 : 2 molar ratio) in good yields. Lithiated 1,2,5-trimethylpyrrole and Me3SnCl forms the compound Me3Sn—CH2—C4H2Me(-5)NMe (8), the reaction of Me2SnCl2 with 2-lithium-1-methylpyrrole gives oligomeric [Me2Sn—C4H2NMe—]x, (6 a). The mass-, NMR, and vibrational spectra have been measured and discussed. The results of the X-ray structure determinations of Me3Sn—NC4H4 (1) and Me2Sn(—NC4Me4)2 (3 a) are compared with the structures of the known dimethylmetal pyrroles of Al, Ga, and In.
    Notes: Monomere Trimethylstannylpyrrole, Me3Sn—R (Me = CH3, R = —NC4H4, —NC4H2Me2-2,5, —NC4Me4-2,3,4,5, —C4H3NMe-1), werden durch Metathese aus Me3SnCl und 1(N)- bzw. 2(C)-lithiierten Pyrrolen synthetisiert. Analog hierzu werden aus Me2SnCl2 und Li—N Pyrroliden (Molverhältnis 1 : 2) die ebenfalls monomeren Dimethylstannylbis(pyrrole), Me2SnR2 (1a - 3a), in guten Ausbeuten erhalten. Einfach lithiiertes 1,2,5-Trimethylpyrrol bildet mit Me3SnCl die Verbindung Me3Sn—CH2—C4H2Me(-5)NMe (8); die Umsetzung von Me2SnCl2 mit 2C-lithiiertem 1-Methylpyrrol ergibt oligomeres [Me2Sn—C4H2NMe—]x (6 a). Die Massen-, Kernresonanz- und Schwingungsspektren werden aufgenommen und diskutiert. Die Ergebnisse der Röntgeneinkristallstrukturanalysen von Me3Sn—NC4H4 (1) und Me2Sn(—NC4Me4)2 (3 a) werden mit den Strukturdaten der bekannten Dimethylmetallpyrrole des Al, Ga und In Verglichen.

    Description / Table of Contents: Studies on Dialkyl Metal Phosphoric and Phosphinic Acid Derivatives of the Elements Aluminium, Gallium, Indium, and Thallium. II. The Vibrational Spectra of the Difluorophosphates and Dichlorophosphates.The vibrational spectra (IR and Raman) of the dimethylmetal difluorophosphates and dichlorphosphates ((CH3)2MOOPX2 with M = Al, Ga, In, Tl and X = F, Cl) are assigned and discussed. The trimer aluminium compounds consist of twelve-membered puckered ring skeletons (symmetry D3), the dimer gallium and indium compounds (liquid or molten) have also puckered ring skeletons, which belong to the point group D2.

    Description / Table of Contents: Crystal and Molecular Structure of Dimeric DimethylaminodimethylindiumDimeric dimethylamino-dimethylindium was prepared by splitting off methane from the adduct Me3In—NHMe2 and characterized by its vibrational spectra. The structure - determined by X-ray analysis - has shown to have the monoclinic space group P21/c with a = 7.601, b = 7.336, c = 14.927 Å and β = 119.9°. Patterson, Fourier and Difference synthesis were used for determing the structure, which was refined by least square analysis to an R value of 0.068.
    Notes: Dimeres Dimethylamino-dimethylindium wurde durch Methanabspaltung aus dem Addukt Me3In—Me2NH dargestellt und schwingungsspektroskopisch charakterisiert. Die Röntgenstrukturanalyse führte zu der monoklinen Raumgruppe P21/c mit a = 7,601, b = 7,336, c = 14,927 Å und β = 119,9°. Die Struktur wurde aus Patterson-, Fourier- und Differenz-Fourier-Synthesen abgeleitet und nach der Methode der kleinsten Fehlerquadrate bis zu einem R-Wert von 0,068 verfeinert.
