多有机环锗烷基汞化合物是从有机氢锗酸Ph n GeH 4- n或二锗烷基Ph 2 n Ge 2 H 4- n(n = 1,2)与二烷基汞R 2 Hg的反应中获得的。如此合成的二或三聚汞的双聚锗酸酯通常表现出较低的稳定性,并且会发生热分解或光分解,从而导致相应的单价(锗烷),二价(亚锗烷)或三价(锗中心自由基)物种以及中间双自由基可以认为是锗双键化合物的极限形式。这样的中间体已经在化学和光谱学上表征。
Under microwave irradiation, alkyl- or arylhalogermanes RnGeX4, (R = Et, Bu, Ph; X = Cl, Br) are obtained by redistribution reactions of R4Ge with GeX4. These experimental conditions permit the synthesis of such compounds in good yield in a few minutes at atmospheric pressure. The direct Friedel-Crafts germylation of benzene and toluene by germanium tetrachloride also has been performed, but yields were low.
