Synthesis of Aminobismuthanes via Me 3 SnCl Elimination

The synthesis of N ‐trimethylstannylamines of the type R N(SnMe 3 )H (stannylated anilines) with the sterically encumbered substituents R such as Ter [terphenyl, 2,6‐bis(2,4,6‐trimethylphenyl)‐phenyl], Ar* [2,6‐bis(diphenylmethyl)‐4‐methylphenyl], and Mes* (supermesityl, 2,4,6‐tri‐ tert ‐butylphenyl) is described. These stannylated anilines were treated with BiCl 3 leading to the formation of R N(H)BiCl 2 (for R = Ter), ( R NH) 3 Bi (for R = Mes*), and R N(BiCl 2 ) 2 (for R = Ar*). The synthesis and structure of the starting material R N(SnMe 3 )H and the new aminobismuthanes are reported.
