Isolation and Reactivity of Stannylenoids Stabilized by Amido/Imino Ligands.

ABSTRACT: The reaction of the lithium aryl(silyl)amide Dipp(ⁱ Pr₃ Si)NLi (Dipp=2,6-ⁱ Pr₂ C₆ H₃ ) with one equivalent of SnCl₂ in THF gave a novel stannylenoid Dipp(ⁱ Pr₃ Si)NSnCl⋅LiCl(THF)₂ . Heating the solution of amidostannylenoid in toluene to 80 °C resulted in dimeric amido(chloro)stannylene [Dipp(ⁱ Pr₃ Si)NSnCl]₂ , which can be converted to bis(amido)stannylene Sn[N(Dipp)(ⁱ Pr₃ Si)]₂ and amido(imino)stannylene Sn[N(Dipp)(ⁱ Pr₃ Si)][IPrN] (IPrN=bis(2,6-diisopropylphenyl)imidazolin-2-imino). Treatment of bis(imino)stannylenoid [IPrN]₂ Sn(Cl)Li with N₂ O resulted in the dimeric co
