Germanium Compounds - an overview | ScienceDirect Topics

Direct synthesis of di- and tetravalent germanium compounds is possible. 1 Thus germanium metal–solvent slurries provide a reactive surface for organic halides (BrCCl 3, CCl 4, CHCl 3, MeI, EtI, etc.) giving organogermanium halides in low yields. 73 Thermally generated germanium atoms also react with organic halides by insertion into carbon–halogen bonds.
