Description
  • Two mixed amido-azido tin(IV) species bearing either C,N-chelating or bulky amido ligands were prepared by the reaction of the corresponding stannylene (e.g., Sn[N(SiMe3)(2)](2) (1) or (L-CN)(2)Sn (2, L-CN = 2-(N,N-dimethylaminomethyl)phenyl)) with Me3SiN3. Both products of the oxidative addition, Sn[N(SiMe3)(2)](3)N-3 (3) and (L-CN)(2)Sn[N(SiMe3)(2)]N-3 (5), respectively, were fully characterized by both multinuclear NMR spectroscopy and XRD analysis. Heating of a mixture of 2 and Me3SiN3 up to 100 degrees C lead to the formation of a novel dimeric species (L-CN)(2)Sn(mu-NSiMe3)(2)Sn(L-CN)(2) (4), where the two tin atoms are bridged by two NSiMe3 ligands, thus forming a four-membered diazadistannacycle. DFT calculations were also carried out to support the proposed reaction mechanisms.
