A study was performed to elucidate the intrinsic factor for the ring deformation of cyclopropabenzene skeletons. The treatment of an overcrowded diaryldilithiogermane, Tbt(Dip)GeLi2 (Tbt = 2,4,6,-tris[bis(trim-ethylsilyl)methyl]phenyl; Dip = 2,6-diisopropylphenyl), generated by exhaustive reduction of the corresponding dibromogermane Tbt(Dip)GeBr2, with 1,2-dibromobenzene resulted in the isolation of the germacyclopropabenzene. The experimental results were in good agreement with those obtained by theoretical calculations.
