The lithiation of Mes2GeH2 with nBuLi in a 1:2 molar ratio at low temperature gives an aggregate 1 of the parent germyllithiated derivative, unreacted nBuLi and ether in a 1:1:1 ratio. Compound 1 was characterized by 1H, 13C and 7Li NMR. Reactions of 1 with D2O and Me3SiCl afford exclusively the monosubstituted derivatives. With PhCHO, we observe the formation of the germylated alcohol 5 and PhCHOHBu. Reaction with Mel is more complex and leads to the dimethylated compound 6 through a single electron transfer mechanism. Transient radical species are detected by an ESR study.
