Synthesis of Aminobismuthanes via Me3SnCl Elimination.

The synthesis of N-trimethylstannylamines of the type RN(SnMe3)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 BiCl3 leading to the formation of RN(H)BiCl2 (for R = Ter), ( RNH)3Bi (for R = Mes*), and RN(BiCl2)2 (for R = Ar*). The synthesis and structure of the starting material RN(SnMe3)H and the new aminobismuthanes are reported. [ABSTRACT FROM AUTHOR]
