Ligand Chemistry of Tellurium

Abstract

Potentially bidentate tellurium ligands having the molecular formula ArTe(CH₂) _nTeAr, (Lⁿ), n=1, 5, 6, 7, 9, 10  and o-C₆H₄,(CH₂TeAr) , (L) are prepared by reacting ArTeNa with 1, n-dibromoalkanes or with o-C₆H₄(CH₂Br)₂.  Changing the reactant ratio from 2:1 to 1:2 resulted In a telluronium salt only in the case of 1,5-dibromopentane. The bromination of some of the bis-tellurides resulted in bis-tribromidesdue to the rupture of the tellurium-aryl bond. The ¹³C N.M.R. spectra are particularly useful in characterisation of these ligands...
