Ein gemischtes, schwereres Si=Ge Analogon eines Vinylanions

Abstract: Die vielseitigen Reaktivitäten von Disileniden und Digermenid, schwereren Analoga von Vinylanionen, haben den Pool an Silicium-und Germaniumverbindungen in den letzten zwei Jahrzehnten mit verschiedensten unerwarteten Strukturmotiven erheblich erweitert. Wir berichten nun über die Synthese eines cyclischen, heteronuklearen Vinylanionanalogons mit einer Si = Ge Bindung, dem Kaliumsilagermenid als stabiles THF-und 18-c-6-Solvat durch KC 8 Reduktion von Germylen-oder Digermenvorläufern. Seine Eignung als Baustein… Show more

“…obtained dianionic species containing E=E bonds (RME=ERM, E=Si, Ge, Sn) by reduction of the corresponding halides. These anionic multiple bonded species have unique chemical utilities including the activation of small molecules and synthesis of novel conjugated systems, heterocycles and cluster compounds [3–11, 12] …”

“…More recently, Scheschkewitz et al. was able to isolate the digermenide (R 2 Ge=GeRM) [7] and silagermenide (R 2 Si=GeRM) [8] . In addition, Power, [9] Aldridge [10] and Cui [11] et al.…”

“…However, the synthesis of such species is extremely challenging, because replacement of a bulky substitute with a metal atom will decrease the kinetic stabilization and thus increase the propensity of them to undergo oligomerization [2] . In fact, only few heavier analogues of vinyl anions (Scheme 1) have been published [3–8] . In seminal works in 2004, the groups of Scheschkewitz [3a] and Sekiguchi [4a] independently reported the first isolated disilenides (R 2 Si=SiRM).…”

“…Recently, the first potassium silagermenide (R 2 Si=GeR′‐K) was isolated by Scheschkewitz et al. and was used for the synthesis of functional silagermenes [3j] . Metallo‐silenides I [9] and II , [10] were synthesized and isolated in our group (Figure 1).…”
