• It is important to determine accurately the concentration of the Grignard reagent in each reaction. The amount of Grignard reagent/GeCl4 is adjusted each time to give exactly a 2:1 ratio of MesMgBr:GeCl4

• The composition of the reaction mixture from the Mes2GeHLi/Mes2GeCl2 coupling reaction can vary depending on the quality of the tert-BuLi used to generate the germyllithium reagent. If the mixture consists of Mes4Ge2HCl/Mes2GeH2/Mes4Ge2H2, the quantity of reagents for chlorination is adjusted based on the Mes4Ge2HCl/Mes2GeH2/Mes4Ge2H2 ratio as determined by 1H NMR spectroscopy. If the mixture consists of Mes4Ge2HCl/Mes2GeCl2, flash chromatography through a 6 silica gel column can be performed at this stage to give pure Mes4Ge2HCl before chlorination
