Lösungsmitteleinflüsse auf die Struktur und Stabilität von Alkalimetallcarbenoiden

The reaction of the lithium aryl(silyl)amide Dipp(iPr3Si)NLi (Dipp=2,6‐iPr2C6H3) with one equivalent of SnCl2 in THF gave a novel stannylenoid Dipp(iPr3Si)NSnCl⋅LiCl(THF)2. Heating the solution of amidostannylenoid in toluene to 80 °C resulted in dimeric amido(chloro)stannylene [Dipp(iPr3Si)NSnCl]2, which can be converted to bis(amido)stannylene Sn[N(Dipp)(iPr3Si)]2 and amido(imino)stannylene Sn[N(Dipp)(iPr3Si)][IPrN] (IPrN=bis(2,6‐diisopropylphenyl)imidazolin‐2‐imino). Treatment of bis(imino)stannylenoid [IPrN]2Sn(Cl)Li with N2O resulted in the dimeric complex [IPrNSn(Cl)OLi]2. All compounds were characterized by NMR, elementary analysis, and X‐ray structural determination.
