Treatment of organotellurium(IV) halides with t-butyl hydroperoxide in 1,4-dioxan, acetic acid, or acetonitrile affords the corresponding organichalides in good to moderate yields presumably as the result of a 1,2-halogen shift.
New aryltellurium trichlorides have been prepared. A method for synthesizing aryltellurium tribromides and triiodides based on the halogenolysis of the corresponding ditellurides is presented. Thiophenoxtellurine was obtained from o-thiophenoxyphenyltellurium trichloride.

Aryl tellurium trichlorides and tribromides undergo condensation reactions with acetone, acetophenone, N-dimethylaniline and resorcinol, giving rise to aryl tellurium dihalides. Aryl tellurium triiodides are not reactive. The dihalides derived from N-dimethylaniline and resorcinol undergo ionic interchange reactions with halide ions. When treated with reducing agents the dihalides derived from N-dimethylaniline

Irradiation of organotellurium(IV) halides in benzene affords the corresponding organichalide by α-elimination, the carbon–halogen bond being formed at ipso-position and in some case retentively. The reaction is not affected by the presence or absence of oxygen and t-butoxy radical.
