Abstract
Halogenation reactions of BbtTe‐TeBbt (Bbt; 2,6‐bis[bis(trimethylsilyl)methyl]‐4‐[tris (trimethylsilyl)methyl]phenyl) with SO~2~Cl~2~, Br~2~, and I~2~ were examined. When 1 equiv of the reagents were used, the corresponding tellurium monohalides were obtained as stable crystalline compounds. Although iodination reaction of BbtTe‐TeBbt using 3 equiv of I~2~ afforded BbtTeI, treatment of BbtTe‐TeBbt with 3 equiv of SO~2~Cl~2~ and Br~2~ gave the corresponding tellurium trihalides, BbtTeX~3~(X = Cl, Br), as stable crystalline compounds. Characterization of the obtained tellurium mono‐ and trihalides was achieved by the spectroscopic and crystallographic analyses, together with theoretical calculations. © 2011 Wiley Periodicals, Inc.
