Synthesis of Bis(Alkyltelluro)Methanes and their Complexation with Cadmium(II)

Abstract

A novel and convenient route for the synthesis of a series of bis(alkyltelluro)methanes (alkyl─ethyl, isopropyl, n-butyl and n-hexyl) is described by one pot methylene insertion reaction using dialkyl ditellurides, sodium borohydride and chloroform. The cadmium(II) complexes of bis(isopropyltelluro)methane were also synthesized. The bis(alkyltelluro)meth-anes were characterized by elemental analysis, ¹H and ¹²⁵Te NMR. The product of the complexation of bis(isopropyl telluro)methane with Cd(II) have been characterized by elemental analysis, ¹H, TGA and FAB mass spectrometry. The dialkyltelluroether ligands may be useful in organic synthesis and their complexes with cadmium(II) can be considered a potential single source of metal-organic chemical vapor deposition (MOCVD) precursors for advanced electronic materials.
