New (2,4,6-Triisopropylphenyl) Hydro-, Halo- and Hydrohalogermanes
摘要:
New hydro-, halo- and hydrohalogermanes of the types IsGeH(3-n)Cl(n) (n = 0, 1, 3, Is = 2,4,6-triisopropylphenyl) and Is(R)GeH2-nXn (n = 0 or 2, X = Cl, F), potential precursors of stable, low-coordinated species of germanium, have been synthesized. All of them are substituted by at least one bulky 2,4,6-triisopropylphenyl group, R being a second Is group, a mesityl, a pentamethylcyclopentadienyl or a fluorenyl group.

The synthesis and structural analysis of the 1,2-bis(ferrocenyl)digermene (E)-Tip(Fc)Ge═Ge(Fc)Tip (Tip = 2,4,6-triisopropylphenyl, Fc = ferrocenyl), a stable crystalline compound, is reported. In this digermene, two ferrocenyl d electron systems are bridged by a Ge═Ge π spacer. As is evident from X-ray crystallographic, spectroscopic, and electrochemical analysis, this 1,2-bis(ferrocenyl)digermene
