Abstract

The trapping of a transient base-stabilized germylenylsilylene by elemental tellurium and arylazide is described. The reaction of the potassium 2-imino-5,6-methylenedioxylphenylgermylidenide [L_iminophenylGeK] (L_iminophenyl = 2-imino-5,6-methylenedioxylphenyl) with the amidinato chlorosilylene [L_amidinateSiCl] {L_amidinate = PhC(NtBu)₂} in THF at –78 °C afforded the transient base-stabilized germylenylsilylene [L_amidinateSiGeL_iminophenyl] (3). It was unstable in solution, but can be trapped by reacting with elemental tellurium and 2,6-diisopropylphenylazide ArN₃ (Ar = 2,6-iPr₂C₆H₃) to form the first base-stabilized germylenyl silaneditelluroate [L_iminophenylGeTeSi(=Te)L_amidinate] (4) and 1,3-diaza-2-silaallylgermylene complex [{L_amidinateSi(NAr)₂}GeL_iminophenyl] (5), respectively. In these reactions, elemental tellurium and ArN₃ insert into the :Si–Ge: bond in 3, followed by oxidation of the Si center with the substrates to form compounds 4 and 5, respectively. Compounds 4 and 5 were characterized by X-ray crystallography.
