✦ Synopsis
Abstract
A new series of organotellurium(IV) compounds based on di(cyclohexylmethyl)telluride (1) (i.e., (C~6~H~11~CH~2~)~2~TeX~2~ and (C~6~H~11~CH~2~)~2~Te(R)X) was prepared by the reaction of compound 1 with halogens, N‐bromosuccinimide, and alkyl halides. Phenylation of (C~6~H~11~CH~2~)~2~TeX~2~ with sodium tetraphenylborate gave di(cyclohexylmethyl)phenyltelluronium tetraphenylborate in good yield. Conductivity measurements in dimethylsulfoxide (DMSO) showed a considerable ionic character of these compounds and they behave as 1:1 electrolytes. ^1^H NMR studies in CDCl~3~ solution indicated that telluronium salts employed in this study are unstable toward reductive elimination. Reaction of di(cyclohexylmethyl)telluride, (C~6~H~11~CH~2~)~2~Te(CH~3~)I, and (C~6~H~11~CH~2~)~2~Te(PhCH~2~)Br with HgX~2~ (X = Cl or Br) afforded 1:1 complexes. All compounds were characterized by elemental analyses and spectroscopic data. © 2007 Wiley Periodicals, Inc.
