Synthesis and Characterization of Some Diorganotellurium (IV) Oximates

Abstract

A number of of tetra-coordinated diorganotellurium(IV) oximates of the type Ar₂TeCl(ONCRR'), Ar₂Te(ONCRR')₂ where Ar = Ph, p-CH₃C₆H₄ and R, R' = Me, Me; Me, Ph; Me, Et; Ph, Ph; and -(CH₂)₅ have been synthesised either by the reaction of diorganotellurium (IV) dichlorides with the appropriate oxime in the presence of triethylamine or by the metathetical reaction of Ar₂TeCl₂ with the corresponding sodium salt of the ligand. The organotellurium(IV) oximate derivatives have been characterized by elemental analysis, IR and NMR spectra, molecular weight and conductance data.
