The new aryldihydrogermyllithium complexes RH2GeLi (R = Ph, Mes) are prepared, in good yields, by metallation of the parent trihydrogermane with t-butyllithium in THF.They are characterized by alkylation reactions with MeI.Some germylation reactions are reported: they lead to the formation of new functional aryldihydrogermanes and aryldigermanes by a nucleophilic substitution.These aryldihydrogermyllithium complexes react also with acyl chlorides RCOCl (R = Ph, Mes) to give new diacyl- and triacyl-germanes.These easily add to the carbonyl group of aromatic aldehydes, thereby giving the corresponding α-germyl alcohols.
