A new universal method was developed for the production of unsymmetrical and symmetrical diaryltellurium dichlorides and dibromides on the basis of the reaction of diaryl ditellurides with arenediazonium ions in the presence of copper(II) halides.
Carbon-13 nuclear magnetic resonance studies of organotellurium compounds. II. Chemical shift trends

13C nmr chemical shifts are reported for some aromatic and aliphatic tellurium compounds.For a given organic group, the shift of the C1 atom varies in the order RTeCl4- >/= RTeCl3 > R2TeCl2 > R2Te > R2Te2, as expected from electronegative considerations.The C2 atom experiences an opposite trend while the C3 and C4 atoms of the ring experience smaller changes.The chemical shifts of para-substituted aromatic tellurium compounds do not show additivity of contributions from the substituents.
Reactions of Diaryltellurides with Some Organic Halides and Sn(IV) Tetraiodide: Electrophilic Cleavage of Te-Allyl Bond

Diaryltellurides, RTeR' (R = R' = C6H5 or p-CH3OC6H4; and R = C6H5, R' = p-CH3OC6H4) react with allyl bromide, cyclohexyl iodide, CH3I, C6H5X (X = Br, I) or SnI4 to give corresponding triorganotelluronium halides.The Te-allyl bond is readily cleved by electrophiles as Br2, I2, ICl, BrCN, ICN.
