Abstract

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 [Liminophenyl GeK] (Liminophenyl = 2‐imino‐5, 6‐methylenedioxylphenyl) with the amidinato chlorosilylene [Lamidinate SiCl] {Lamidinate = PhC(N t Bu)2 } in THF at –78 °C afforded the transient base‐stabilized germylenylsilylene [Lamidinate SiGeLiminophenyl ] (3 ). It was unstable in solution, but can be trapped by reacting with elemental tellurium and 2, 6‐diisopropylphenylazide ArN3 (Ar = 2, 6‐ i Pr2 C6 H3 ) to form the first base‐stabilized germylenyl silaneditelluroate [Liminophenyl GeTeSi(=Te)Lamidinate ] (4 ) and 1, 3‐diaza‐2‐silaallylgermylene complex [{Lamidinate Si(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. Abstract : The transient base‐stabilized germylenylsilylene 1 was trapped by elemental tellurium and 2, 6‐diisopropylphenylazide to form the first germylenylsilaneditelluroate 2 and 1, 3‐diaza‐2‐silaallylgermylene complex 3 .
