Abstract
The reactions of hydrogermylation of allylsilanes and -germanes R3MAll (M = Si, Ge; R = Cl, EtO, Me) by hydridgermanes R3GeH (R = Cl, Me) and trichlorogermane ether 2Et2O·HGeCl3 were studied. It has been established that small amounts of mono- (β- and γ-adducts) and double germylation products and, mainly, polymers are formed in reactions with ether. During hydrogermylation of Me3SiAll with trichlorogermane, insignificant amounts of β-adduct were recorded, but mainly in the entire series of experiments with Cl3GeH, γ-adducts are formed. In the catalytic reactions of allylsilanes and -germanes with trimethylgermane, exclusively γ-adducts are formed regardless of the framing of silicon and germanium atoms. A scheme of the possible course of the studied reactions is proposed. The identification of synthesized compounds was carried out using the methods of gas-liquid chromatography, 1Н, 13С NMR spectroscopy and chromatography-mass spectrometry
