Direct synthesis of organotrichlorogermanes by the reaction of elemental germanium, hydrogen chloride, and alkene

The reaction of elemental germanium, hydrogen chloride, and ethylene with copper(I) chloride catalyst gave ethyltrichlorogermane with a 66% selectivity, tetrachlorogermane also being formed. The addition of tetrachlorogermane to the reaction system increased the formation rate of ethyltrichlorogermane. The reaction of germanium, tetrachlorogermane, and butadiene resulted in the formation of 1,1-dichlorogermacyclopent-3-ene. These results indicate the intermediacy of dichlorogermylene, which is formed by the reaction of elemental germanium with tetrachlorogermane. In place of ethylene, allyl chloride was fed with hydrogen chloride. Allyltrichlorogermane was obtained with a 92% selectivity together with a small amount of tetrachlorogermane. It is highly plausible that the formation of allyltrichlorogermane is caused by the insertion of dichlorogermylene intermediate to the carbon - chlorine bond of allyl chloride.

Thermal transformations of phenyltrichlorogermane in the gas phase

Pyrolysis of PhGeCl3 and its mixtures with allyl chloride and isoprene in the temperature range 500-680°C was investigated. PhGeCl3 vigorously decomposes at temperatures higher 600°C, and its decomposition involves both dichlorogermylenes and trichlorogermyl radical. Pyrolysis of mixtures of PhGeCl3 with isoprene or allyl chloride yields respectively trichloro(1,2-dimethyl-2-propenyl)germane, isopentyltrichloro germanes, and 1,1-dichloro-3-methyl-1-germacyclo-3-pentene or allyltrichlorogermane. A mechanism of formation of these products is proposed.
