The dibenzo-7-dimethylgermanorbornadiene Me₂GeA (A = C₁₄H₁₀) has been synthesized in one step by treatment of MgA路3THF with Me₂GeCl₂ in tetrahydrofuran (鈭?5 掳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.
