Silyl tellurides react with organichalides to give the corresponding organotellurium compounds and silyl halides in good to excellent yields. Substitution proceeds in polarsolvents, such as acetonitrile, but not in nonpolar solvents under identical conditions. The leaving group also plays a significant role, with alkyl bromides being the most reactive, alkyl chlorides less so and alkyl iodides the

Silyl tellurides reacted with alkylhalides under mild thermal conditions to give the corresponding alkyl tellurides and silylhalides in good to excellent yields. Substitution took place much faster in polar solvents, such as acetonitrile, than that in non-polarsolvents. After removal of the volatile silyl halides and solvent under vacuum, the essentially pure divalent organotellurium compounds were
