Glockling et al.[1] reported that the reaction of tetrachlorogermane with vinylmagnesium chloride yielded exclusively the complete vinylation products: tetravinylgermane, hexavinyldigermane, and octavinyltrigermane [1]. We showed that the reaction of a freshly prepared solution of vinylmagnesium chloride in THF (without separation of the precipitate) with a solution of GeCl4 in THF yields a mixture of vinylchlorogermanes of various ...
