Isolation and Reactivity of Stannylenoids Stabilized by Amido/Imino Ligands

The reaction of the lithium aryl(silyl)amide Dipp(( i )Pr(3)Si)NLi (Dipp=2,6‐( i )Pr(2)C(6)H(3)) with one equivalent of SnCl(2) in THF gave a novel stannylenoid Dipp(( i )Pr(3)Si)NSnCl⋅LiCl(THF)(2). Heating the solution of amidostannylenoid in toluene to 80 °C resulted in dimeric amido(chloro)stanny...

Sumario:The reaction of the lithium aryl(silyl)amide Dipp(( i )Pr(3)Si)NLi (Dipp=2,6‐( i )Pr(2)C(6)H(3)) with one equivalent of SnCl(2) in THF gave a novel stannylenoid Dipp(( i )Pr(3)Si)NSnCl⋅LiCl(THF)(2). Heating the solution of amidostannylenoid in toluene to 80 °C resulted in dimeric amido(chloro)stannylene [Dipp(( i )Pr(3)Si)NSnCl](2), which can be converted to bis(amido)stannylene Sn[N(Dipp)(( i )Pr(3)Si)](2) and amido(imino)stannylene Sn[N(Dipp)(( i )Pr(3)Si)][IPrN] (IPrN=bis(2,6‐diisopropylphenyl)imidazolin‐2‐imino). Treatment of bis(imino)stannylenoid [IPrN](2)Sn(Cl)Li with N(2)O resulted in the dimeric complex [IPrNSn(Cl)OLi](2). All compounds were characterized by NMR, elementary analysis, and X‐ray structural determination.
