“…In 2020, Sun, Li, Wang and co-workers presented new lithium germylidenide and silylene-germylene complex (Scheme 3-20). 130 The reduction of β-diketiminato germanium(II) chlorides 3-20-1 with Li gave the corresponding germylidenide complex 5CNGe5 and 5CNGe6, respectively. XRD analysis revealed that the almost planar C3NGe ring with the interior angle summation (Σ int) of 539.8° (5CNGe5) and 550.0° (5CNGe6).…”

“…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.…”

Reactions of silicon and germanium dichlorides L•ECl 2 (E = Si, L = IPr; E = Ge, L = dioxane) with the phosphinoamidinato-supported disilylene ({k 2 (N,P)-NNP}Si) 2 resulted in formal tetrylene insertions into the SiÀ Si bond. In the case of the reaction with silylene, two products were isolated. The first product ({k 2 (N,P)-NNP}Si) 2 SiCl 2 , is the formal product of direct SiCl 2 insertion into the SiÀ Si bond of ({k 2 (N,P)-NNP}Si) 2 and thus features two separated silylamido silylene centers. Over time, migration of the SiCl 2 group to a lateral position afforded the second product, the disilylene {k 2 (Si,P)À SiCl 2 NNP} SiÀ Si{k 2 (N,P)-NNP}. In contrast, insertion of GeCl 2 resulted only in the isolation of the germanium analogue of {k 2 (Si,P)À SiCl 2 NNP}SiÀ Si{k 2 (N,P)-NNP}, containing a Ge atom in the central position namely, compound {k 2 (Si,P)À SiCl 2 NNP} GeÀ Si{k 2 (N,P)-NNP}, which is a rare example of a silylenegermylene. Finally, reaction of disilylene ({k 2 (N,P)À NNP}Si) 2 with SiCl 4 and SiHCl 3 led to the formation of the new bis(silyl)silylene, ({NNP}SiCl 2 ) 2 Si:. All four new products from these insertion reactions have been characterized by multinuclear NMR and single-crystal X-ray diffraction studies.

“…It is because the reactive Ë‐Ë' moiety makes such complexes difficult to isolate. Thus far, only a handful of examples were reported, where the sterically hindered germylidenide anions [:G̈e{C(R 1 )C(R 2 )C(R 1 )N(Ar)}] – (R 1 = Me/Ph, R 2 = H/Ph) reacted with the β‐diketiminato chlorostannylene and amidinato chlorosilylene to form the corresponding base‐stabilized germylenylstannylene and –silylene . Interestingly, their reactivity was never reported.…”

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.
