A Base‐Stabilized Germylenyl Silaneditelluroate and 1,3‐Diaza‐2‐silaallylgermylene

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 iminophenyl GeK] (L iminophenyl = 2-imino-5,6-methylenedioxylphenyl) with the amidinato chlorosilylene [L amidinate SiCl] {L amidinate = PhC(NtBu) 2 } in THF at-78°C afforded the transient base-stabilized germylenylsilylene [L amidinate SiGeL iminophenyl ] (3). It was unstable in solution, but can be trapped by reacting with elemental tellurium and 2,6-diiso-[a] Dr.

Reactions of main group compounds with azides forming organic nitrogen-containing species

“…In 2020, the So group reported the reaction between a transient base-stabilized germylenylsilylene Si19 and azides (Scheme 73). 128 Adding two equivalents of DipN 3 into the toluene solution of Si19 gave the 1,3-diaza-2-silaallylgermylene complex Si19-P in a yield of 67% with the evolution of N 2 . Formation of Si19-P indicates the insertions of two nitrenes into the Ge-Si bond.…”

Synthesis of Cationic Silaamidinate Germylenes and Stannylenes and the Catalytic Application for Hydroboration of Pyridines

“…The Ge1–Cl1 bond length of 2.367(12) Å was longer than a typical single bond (2.06–2.32 Å) . It is noted that a germylene compound incorporating the same silaamidinate ligand was reported by So et al…”

The Insertion of EII and EIV Chlorides (E=Si, Ge) into the Si−Si Bond of Disilylene

“…The first isolated example, compound 13 , prepared by salt metathesis of a germylene anion and a chlorosilylene, was only reported in 2020 by Wang and co‐workers (Figure 6). [27] A similar base‐stabilized silylene‐germylene 14 was observed as a transient species that decomposes in solution even at −30 °C [28] . Consequently, compound 12 is only the second isolated, fully characterized example of this interesting class of low‐valent compounds.…”
