Silyl tellurides react with organic halides to give the corresponding organotellurium compounds and silyl halides in good to excellent yields. Substitution proceeds in polar solvents, 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 least reactive. After removal of the volatile silyl halides and solvent under vacuum, the essentially pure organotellurium compounds, which can be used directly as precursors for carbocations, carbanions, and carbon-centered radicals, were obtained.
Experimental and theoretical studies on formal σ-bond metathesis of silyl tellurides with alkyl halides

, p. 664 - 670 (2008/02/06)
Silyl tellurides reacted with alkyl halides 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 no
