在四氢呋喃(−)中用Me_2GeCl2与Me_2Ge_2反应，一步合成了二苯并-7-二甲基锗-冰片二烯Me2GeA(A=C14H10)，产率为69%。Me2GeA在甲苯中的热分解导致双环骨架有效地扩展到dibenzo-7，8-tetramethyldigermabicyclo[2.2.2]octadiene(Me2Ge)2A，以71%的产率分离(以锗为基础)。用单晶X射线衍射法对双环化合物Me2GeA和(Me2Ge)2A进行了表征，并对其结构进行了讨论。
The dibenzo-7-dimethylgermanorbornadiene Me2GeA (A = C14H10) has been synthesized in one step by treatment of MgA·3THF with Me2GeCl2 in tetrahydrofuran (−35 °C) and isolated in 69% yield. The thermolysis of Me2GeA in toluene leads to the effective expansion of the bicyclic framework to the dibenzo-7,8-tetramethyldigermabicyclo[2.2.2]octadiene (Me2Ge)2A, isolated in 71% yield (based on germanium). The bicyclic compounds Me2GeA and (Me2Ge)2A have been characterized by single-crystal X-ray diffraction studies and their structures discussed.
