redistribution of the pairs of substituents Cl/Br, Cl/I and Br/I between the (CH 3 ) 2 Ge and variousmethylphosphorusmoieties [CH 3 P, CH 3 P (O) and CH 3 P(S)] using quantitative proton nuclear magnetic resonance to assay the equilibrated mixtures. By simple stoichiometric computations, additional equilibrium constants were calculated for the pairs of substituents Cl/SCH 3 , Br/SCH 3 , Cl/OC 6

Abstract He(I) photoelectron spectra are reported for the series of compounds (CH 3 ) 3 GeI, (CH 3 ) 2 GeHI, CH 3 GeH 2 I and (CH 3 ) 2 GeI 2 , as well as for (CF 3 ) 3 GeI, (CF 3 ) 2 GeI 2 and CF 3 GeI 3 . He(II) photoelectron spectra are also reported for all of the perfluoromethyl compounds. Assignments are proposed on the basis of semi-empirical CNDO/2 calculations, band shapes and changes of relative

inorganic germanium(IV) hydroxides ((CH3)nGe(OH)4−n; n=0,1,2, or 3) with halide ions (X=Cl−, Br−, or I−) to form halide complexes ((CH3)nGeX4−n) in aqueousacidicsolution has been investigated by liquid–liquid extraction, solid–liquid distribution (ion exchange), and 1H NMR spectrometry. It has been found that methylgermanium moieties are hard Lewis acids similarly to inorganic germanium(IV), because the

Germanium vapor (atom) when co-condensated with THF at 77 K was found to be reactive toward organic halides. Several organogermanium halides were prepared by the addition of organic halides to the resultant germanium atom-THF slurry at ambient temperatures.
发现锗蒸气(原子)在 77 K 与 THF 共缩合时对有机卤化物具有反应性。通过在环境温度下将有机卤化物添加到所得锗原子-THF浆液中,制备了几种有机卤化锗。
Chemistry of Germanium Atoms. II. Reactions of Thermally Evaporated Germanium Vapor with Organic Halides
Thermally generated germaniumatoms were found to react with organic halides by insertion into carbon–halogen bonds. The resulting germylenes abstracted halogens from organic halides to form trihalogermyl derivatives. Tetrahalogermanes were also formed by the abstraction of halogens with germaniumatoms.
