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.
Organotrichlorogermane synthesis by the reaction of elemental germanium, tetrachlorogermane and organic chloride via dichlorogermylene intermediate

Organotrichlorogermanes were synthesized by the reaction of elemental germanium, tetrachlorogermane and organic chlorides, methyl, propyl, isopropyl and allyl chlorides. Dichlorogermylene formed by the reaction of elemental germanium with tetrachlorogermane was the reaction intermediate, which was inserted into the carbon-chlorine bond of the organic chloride to give organotrichlorogermane. When isopropyl or allyl chloride was used as an organic chloride, organotrichlorogermane was formed also in the absence of tetrachlorogermane. These chlorides were converted to hydrogen chloride, which subsequently reacted with elemental germanium to give the dichlorogermylene intermediate. The reaction of elemental germanium, tetrachlorogermane and organic chlorides provides a simple and easy method for synthesizing organotrichlorogermanes, and all the raw materials are easily available.

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.
Reactions of Tetrachlorogermane with Allyl Chloride and Methallyl Chloride in the Presence of Hexachlorodisilane as an Initiator

Allyl chloride and methallyl chloride react with tetrachlorogermane in the presence of hexachlorodisilane to give as major products allyltrichlorogermane and allyltrichlorosilane in the former case and (2-methyl-2-propenyl)trichlorogermane and (2-methyl-2-propenyl)trichlorosilane in the latter case. The reaction schemes are proposed and discussed.
