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 [LiminophenylGeK] (Liminophenyl = 2‐imino‐5,6‐methylenedioxylphenyl) with the amidinato chlorosilylene [LamidinateSiCl] {Lamidinate = PhC(NtBu)2} in THF at –78 °C afforded the transient base‐stabilized germylenylsilylene [LamidinateSiGeLiminophenyl] (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 [LiminophenylGeTeSi(=Te)Lamidinate] (4) and 1,3‐diaza‐2‐silaallylgermylene complex [{LamidinateSi(NAr)2}GeLiminophenyl] (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.
