Selective Chlorination of Germanium Hydrides
Hafner, Thomas,Torvisco, Ana,Traxler, Michael,Uhlig, Frank,Wolf, Melanie
, p. 1876 - 1881 (2020)
Methods for the selective chlorination of organogermylhydrides are given by the selective functionalization of organogermylhydrides of types R3GeH, R2GeH2 and RGeH3 (R = alkyl, aryl). The use of trichloroisocyan
A computational study of the fluctional behaviour of group 14 substituted ortho -semiquinone radicals
Ingold,Dilabio, Gino A.
, p. 235 - 240 (2011/04/23)
The dynamics of the 1,4-migration of some O-substituted 3,5-di-tert-butyl-ortho-semiquinone radicals have been calculated by density-functional theory (DFT). There is very good agreement in the rate constant and Arrhenius parameters between these calculations and experimental values for migration of H, D, and the Me3Si group. For the Me 3Sn group, the calculations indicate an incredibly fast migration (k293K = 2.0 × 1012 s-1), a result that is consistent with experimental data (k293K > 109 s-1). Other O-substituents examined by DFT and compared with experimental data were H3C and Me2ClSn.
New (diarylgermyl)lithiums
Castel,Riviere,Satge,Ko
, p. 205 - 210 (2008/10/08)
The new (diarylgermyl)lithiums R2GeHLi (2; R = phenyl, mesityl) were prepared in good yields by hydrogermolysis reactions of tert-butyllithium in THF. The stability of compounds 2 depends on the nature of the R group and the solvent. For R = Ph, in the presence of an amine (Et3N or Et2NMe), the same reaction leads to the formation of the polygermanes H(GePh2)nH (n = 2-4). The characterization of compounds 2 by IR and 1H and 13C NMR spectroscopy and their complexation with a crown ether are also reported. They are characterized by deuterolysis and alkylation reaction (with MeI and Me2SO4). Their germylation reactions with Ge-Cl reagents constitute a convenient way for synthesizing organo-hydropolygermanes. Compounds 2 also react with acyl chlorides to give new germyl ketones, R2HGeCOR′, and the unexpectedly stable β-germyl diketone Ph2Ge(COMes)2.
