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.
