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 alpha-germyl alcohols.

The photolysis of Si,Si-di-tert-butyltetramesitylsiladigermirane in the presence of methylmagnesium iodide at 15°C has been investigated. Five products were isolated and identified from the complex product mixture: mesityldimethylgermane, dimesitylmethylgermane, (di-tert-butylmethylsilyl)mesitylmethylgermane, meta-(di-tert-butylmethylsilyl)toluene, and para-(di-tert-butylmethylsilyl)toluene. The characterization
