Synthesis and structure of azobenzenes bearing silyl, germyl, and stannyl groups at 2-position
Azobenzenes, 2-(R2RMC6H4N)-R-1-M-2=NPh (M = Si (1a-c), Ge (7), and Sn (8)), were synthesized by reactions of 2-lithioazobenzene (6) with the corresponding chloro compounds, (R2RMCl)-R-1-M-2, respectively, in good to moderate yields. The crystal structure of 1c was established by the X-ray crystallographic analysis.
