Trichlorogermane with olefins

Trichlorogermane reactions with olefins and acetylenes, including functionally substituted compounds, are one of the basic methods of obtaining organogermanium derivatives. Trichlorogermane adds easily in the absence of any catalyst to olefinic and acetylenic... 

A detailed study of the reactions of trichlorogermane with unsaturated compounds was performed . It became clear that among selected olefins only 1-heptene forms the anti-Markovnikov adduct in the reaction with trichlorogermane. In contrast to the generally accepted opinion, in the reactions with 1-methylcyclohexene (equation 11), styrene (equation 12), 2,3-dimethyl-l-butene (equation 13) and isobutene (equation 14) both regioisomers 4 and 5, 6 and 7, 8 and 9, and 10 and 11 appear in commensurable amounts (together with oligomeric products see later, equation 16).
