Synthesis and Isolation of New Germanium(II) Compounds and of Free Germylenes

Meller, Anton,Graebe, Claus-Peter

, p. 2020 - 2029 (2007/10/02)

The bis(aryloxy)germylenes 1-4 and the diaminogermylenes 5-10 are obtained from GeCl2-dioxane and lithiated, ortho-substituted phenols and sterically hindered amines (1:2), resp.Compounds R(Me3Si)N-Ge-OtBu (13-15) are formed if the amines are lithiated with tert-butyllithium in n-hexane/THF.Dilithiated ethylenediamines lead to diazagerma(II)cyclopentanes 16 and 17.The amino(halo)germylenes 19 and 20 are obtained from GeX2-dioxane (X = Cl, Br) and lithiated (2,6-dialkylphenyl(trimethylsilyl)amines (1:1).
