  Acetylene-Linked Bis(germaethenes):  The First Molecules with Conjugated Germanium−Carbon Double Bonds¹

  摘要：

  In solution, the digermene Ar2Ge=GeAr2 (Ar = 2-tBu-4,5,6-Me3C6H) partly dissociates into two molecules of the germylene Ar2Ge:. The reaction of this digermene with some 1,3-diynes (RC equivalent to C-)(2) Leads to the formation of the acetylene-linked bis(germaethenes) Ar2Ge=C(R)C equivalent to C(R)C=GeAr2 (R = n-C4H9 (6a), C6H5 (6b)). The conjugation between the two Ge=C units is reflected by the positions of the UV/vis absorptions at Longest wavelengths of 518 (6a) and 595 (6b) nm. An X-ray structure analysis of 6a reveals a nearly linear C-4 skeleton and short Ge=C bond lengths of 1.819(2) Angstrom.
