, 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

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.

The disproportionation reaction of diaryl ditellurides with sodium hydroxide under phase transfer conditions at room temperature is described for the first time.The phase transfer catalyst used is 2HT-75, a trade name for a mixture of dialkyldimethylammonium chlorides.The intermediates aryl tellurolates react "in situ" with alkyl halides to give the corresponding alkyl aryl tellurides (ArTeR) in 52-72percent yield.The following compounds were prepared: Ar = C6H5, R = CH3(CH2)3CH2,(CH3)2CHCH2CH2, (CH3)2CHCH2, CH3CHBrCH2CH2, CH3(CH2)8CH2, C6H5CH2, ClCH2, C6H5CH2CH2, CH2=CHCH2, C6H5CH=CHCH2, C6H5SeCH2, ; Ar = p-CH3C6H4, R = CH3(CH2)2CH2; Ar = p-CH3OC6H4, R = CH3(CH2)2CH2; Ar = p-C2H5OC6H4, R = CH3(CH2)2CH2; Ar = 2-naphthyl, R = CH3(CH2)2CH2.
